AURORA 17719 - Reference Information

Introduction

5-oxo-pyrrolidine-3-carboxylic acid is an important class of pharmaceutical intermediates, among them, 1-benzyl-5-oxo-pyrroline-3-carboxylic acid is an important intermediate for the preparation of the anti-Alzheimer's drug nelacetam
. Nelacitam is a new type of pyrrolidone derivatives, which can improve brain energy metabolism and nerve transmission function, and can significantly improve the function of the cholinergic system in the brain.

preparation

itaconic acid (18g,0.138mol) and benzylamine (14.8g,0.138mol) were placed in a reaction flask, under the protection of N2, raise the temperature
to 130 ℃, slowly melt, stir, react for 2.5h, stop heating, and cool to 100 ℃, add 10% NaOH solution
10% ml under stirring, cool to room temperature, wash the water layer with ethyl acetate, drop into the water layer with hydrochloric acid solution, there are a large number of white solid, to PH = 1-2, filtered, washed with water to PH about 6 to give a white granular solid 25.1g, yield 82.9%.
