Abstract :The synthesis of 2-[2-insert ignore into journalissuearticles values(3,4,5-trimethoxybenzoyloxy);ethyl]pyrrolidine hydrochloride was performed using 2-insert ignore into journalissuearticles values(2-hydroxyethyl);pyrrolidine as a starting material. Before the O-acylation reaction with 3,4,5-trimethoxybenzoyl chloride, the amino group was protected using benzyl chlorocarbonate. The removal of the blocking group was carried out in modified conditions, avoiding the alcoholysis of the ester bond. The final product was separated from its structural isomer by precipitation as its hydrochloride salt. Some steps of the synthesis were controlled by GC-MS. The identification of the respective compounds was performed by mass spectra analyses and confirmed by 1H NMR, 13C NMR, IR and elemental analyses.
