Chemical Properties

Light yellow solid

Uses

4’-Methylbiphenyl-2-carboxylic Acid is used in the synthesis of angiotensin II receptor antagonists used as potent orally active antihypertensives.

General Description

4′-Methyl-2-biphenylcarboxylic acid (4′-Methyl-bi-phenyl-2-carboxyl-ic acid) can be synthesized by reacting 4′-methylbiphenyl-2-carbonitrile with methanol and 30% NaOH solution. Its crystal structure has been characterized by the centrosymmetric hydrogen-bonded dimers.

Purification Methods

Crystallise the acid from toluene or *C6H6 (m 147-148o). [Beilstein 9 H 677, 9 IV 2523.]

Check Digit Verification of cas no

The CAS Registry Mumber 7148-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,4 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7148-03:
(6*7)+(5*1)+(4*4)+(3*8)+(2*0)+(1*3)=90
90 % 10 = 0
So 7148-03-0 is a valid CAS Registry Number.

Synthesis method of 4-bromomethyl-2-methyl formate biphenyl

-

Paragraph 0025-0028; 0032-0035, (2021/07/14)

The invention discloses a synthesis method of 4-bromomethyl-2-methyl formate biphenyl. The method comprises the following steps: performing bromination reaction in a mode of synchronously dropwise adding bromine and hydrogen peroxide, re-oxidizing hydrobromic acid formed after the reaction into bromine, and performing bromination reaction again, so that the bromine can fully participate in the reaction so as to reduce the use amount of bromine raw materials and improve the yield of the 4-bromomethyl-2-methyl formate biphenyl, waste difficult to treat cannot be generated, hydrogen peroxide is cheap and easy to obtain, and the production cost is remarkably saved.

Mechanochemical-Cascaded C-N Cross-Coupling and Halogenation Using N-Bromo- And N-Chlorosuccinimide as Bifunctional Reagents

Bera, Shyamal Kanti,Mal, Prasenjit

, p. 14144 - 14159 (2021/09/13)

Exploration of alternative energy sources for chemical transformations has gained significant interest from chemists, and mechanochemistry is one of those sources. Herein, we report the use of N-bromosuccinimides (NBS) and N-chlorosuccinimides (NCS) as bifunctional reagents for a cascaded C-N bond formation and subsequent halogenation reactions. Under the solvent-free mechanochemical (ball-milling) conditions, the synthesis of a wide range of phenanthridinone derivatives from N-methoxy-[1,1′-biphenyl]-2-carboxamides is accomplished. During the reactions, NBS and NCS first assisted the oxidative C-N coupling reaction and subsequently promoted a halogenation reaction. Thus, the role of NBS and NCS was established to be bifunctional. Overall, a mild, solvent-free, convenient, one-pot, and direct synthesis of various bromo- and chloro-substituted phenanthridinone derivatives was achieved.

Visible-Light-Induced Arene C(sp 2)-H Lactonization Promoted by DDQ and tert -Butyl Nitrite

supporting information, p. 261 - 266 (2020/02/18)

A visible-light photocatalytic aerobic oxidative lactonization of arene C(sp 2)-H bonds proceeds in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and tert -butyl nitrite (TBN). Under the optimized conditions, a range of 2-arylbenzoic acids is converted into the corresponding benzocoumarin derivatives in moderate to excellent yields. This method is characterized by its atom economy, mild reaction conditions, the use of a green oxidant and metal-free catalysis.
