Uses

Used in Pharmaceutical Industry:
4-fluoro-2-Methoxy-5-nitroaniline is used as a reagent for the synthesis of anticancer drugs, specifically in the preparation of Mereletinib. Mereletinib is a potent and selective inhibitor of the fibroblast growth factor receptor (FGFR) family, which plays a crucial role in various types of cancer cell growth and survival. By targeting FGFR, Mereletinib can effectively inhibit tumor growth and progression, making it a valuable therapeutic option for cancer patients.
In addition to its use in the synthesis of Mereletinib, 4-fluoro-2-Methoxy-5-nitroaniline may also have potential applications in the development of other pharmaceutical compounds due to its unique chemical properties. Its ability to form various functional groups and interact with different molecular targets makes it a promising candidate for further research and development in the pharmaceutical field.

Synthesis

4-FLUORO-2-METHOXYANILINE(551 mg, 3.90 mmol) is dissolved in dichloromethane (39.0 mL), concentrated sulfuric acid (1.85 mL) is added dropwise with stirring under ice-cooling, and then concentrated nitric acid (267 μL, 5.85 mmol) is added dropwise. After stirring for 3 hours under ice-cooling, saturated aqueous sodium bicarbonate was added until pH 8 was reached. After washing with saturated aqueous sodium bicarbonate solution, washing with saturated brine, the organic layer was dried over sodium sulfate and evaporated under reduced pressure to obtain 675 mg of the 4-fluoro-2-Methoxy-5-nitroaniline (yield 93%).

Check Digit Verification of cas no

The CAS Registry Mumber 1075705-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,5,7,0 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1075705-01:
(9*1)+(8*0)+(7*7)+(6*5)+(5*7)+(4*0)+(3*5)+(2*0)+(1*1)=139
139 % 10 = 9
So 1075705-01-9 is a valid CAS Registry Number.

Optimization and Scale-Up of the Continuous Flow Acetylation and Nitration of 4-Fluoro-2-methoxyaniline to Prepare a Key Building Block of Osimertinib

K?ckinger, Manuel,Wyler, Benjamin,Aellig, Christof,Roberge, Dominique M.,Hone, Christopher A.,Kappe, C. Oliver

, p. 2217 - 2227 (2020)

The development of a scalable telescoped continuous flow procedure for the acetylation and nitration of 4-fluoro-2-methoxyaniline is described. A subsequent batch deprotection then affords 4-fluoro-2-methoxy-5-nitroaniline, a key building block in the synthesis of osimertinib, a third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that is used for the treatment of nonsmall-cell lung carcinomas carrying EGFR-TKI sensitizing and EGFR T790M resistance mutations. The hazards associated with nitration of organic compounds, such as thermal runaway and explosivity of intermediates, make it difficult to scale up nitrations to industrial quantities, particularly within large-scale batch reactors. In this study, we investigated an acetic acid/aqueous nitric acid mixture as a predominantly kinetically controlled nitration regime and a water-free mixture of acetic acid, fuming nitric acid, and fuming sulfuric acid (oleum) as a mass-transfer-limited nitration regime. A modular microreactor platform with in-line temperature measurement was utilized for the nitration. Furthermore, we identified that it was necessary to protect the amine functionality through acetylation to avoid side reactions. The process parameters and equipment configuration were optimized at laboratory scale for the acetylation and nitration to improve the product yield and purity. The two steps could be successfully telescoped, and the laboratory-scale flow process was operated for 80 min to afford the target molecule in 82% isolated yield over two steps, corresponding to a throughput of 25 mmol/h. The developed flow process was then transferred to an industrial partner for commercial implementation and scaled up by the use of higher flow rates and sizing-up of the microreactor platform to pilot scale to afford the product in 83% isolated yield, corresponding to a throughput of 2 mol/h (0.46 kg/h).

Improvements in the Synthesis of the Third-Generation EGFR Inhibitor Osimertinib

Alivertis, Dimitrios,Skobridis, Konstantinos,Voulgari, Pinelopi

, (2021/10/19)

Osimertinib, a third generation potent and specific EGFR inhibitor is an important drug against many forms of cancer. It was synthesized by an improved and highly efficient protocol, revisiting the classical synthetic process and modifying parameters, such as solvents, temperature, reagents, and reaction time. A cost-effective, environmentally friendly methodology for the synthesis of osimertinib was established, which gave shorter reaction times, saved labor by eliminating purification steps through column chromatography, and enhanced yields. Four of the seven steps in total, were proceeded quantitatively or almost quantitatively (ca. 98 %). This synthetic protocol provides a very high overall yield, up to 68 %. In addition, the entire approach enables the preparation of osimertinib analogues and could be extended in the synthesis of other structurally similar bioactive compounds.
