General Description

2-[[6-[(3R)-3-tert-butoxycarbonylamino-1-piperidinyl]-3,4-dihydro-2,4-dioxo-3-methyl-1(2H)-pyrimidinyl]methyl]benzonitrile, also known as TBOA, is a chemical compound used as a selective antagonist for excitatory amino acid transporters. It has been studied for its potential therapeutic applications in the treatment of neurological and psychiatric disorders, as well as in cancer treatment. TBOA is known to inhibit the reuptake of glutamate, an important neurotransmitter in the brain, and has been shown to have neuroprotective effects in certain animal models. Its precise mechanisms of action and potential side effects in humans are still under investigation, but it is considered a promising candidate for further drug development and research in the field of neuroscience and medicine.

Preparation method of alogliptin benzoate

The invention discloses a preparation method of alogliptin benzoate. Main starting materials of the preparation method are 6-chloro-3-methyluracil, o-cyanobenzyl bromide, (R)-3-Boc-aminopiperidine andbenzoic acid. According to the method, all indexes meet the specification, meanwhile, dangerous reagents such as sodium hydride and highly toxic methyl iodide are prevented from being used in the reaction process, the requirement for the operation process is not strict, and water-free and oxygen-free conditions are not needed; a high-boiling-point mixed solvent is not used in the reaction, and the solvent is easy to recycle; the selected starting materials are available in the market and easy to obtain, and large-scale production is facilitated; in addition, starting materials or intermediates in the synthetic route are good in stability and convenient to store and control, and genotoxic impurities are avoided in the reaction process; and the synthesis process is environment-friendly.

Simple preparation method of alogliptin benzoate

The invention relates to an alogliptin benzoate preparation method, which comprises that 3,3-dihalogenated-N-methyl acrylamide sequentially reacts with (R)-3-Boc-aminopiperidine and 2-cyano benzylamine to prepare (R)-3-(3-Bocamino)piperidine-1-yl-3-(2-cyano)benzylamino-N-methacrylamide, the obtained material reacts with a carbonylation reagent to prepare alogliptin, and the alogliptin and benzoicacid are subjected to salt forming to prepare alogliptin benzoate. According to the present invention, the method has advantages of inexpensive and easily available raw materials, simple operation andless wastewater, and is suitable for the industrial production of alogliptin benzoate.

Alogliptin benzoate preparation method

The present invention provides an alogliptin benzoate preparation method, which comprises treating an intermediate IV reaction solution, and specifically comprises: heating the intermediate IV reaction solution to a temperature of 50-80 DEG C, adding a diluted alcohol while hot, cooling to a temperature of 0-40 DEG C to make the crystal be crystallized, adding water after a lot of the crystals are crystallized, carrying out stirring washing, filtering, and drying to obtain the intermediate IV. According to the present invention, the intermediate IV is prepared by using the one-pot method, a certain amount of the diluted alcohol is added at the high temperature, the saturated solution is formed after the cooling, and the cooling is continuously performed to crystallize, such that the crystal caking problem caused by the direct water precipitation is avoided, the intermediate IV crystal is uniformly dispersed, sticking on the wall and the agglomeration do not exist, the sticking onto the stirring slurry does not exist, the operation is convenient, and the method is suitable for industrial production.
