Abstract

Esta invención proporciona un procedimiento para preparar clorhidrato de gemcitabina que comprende desbloquear ß-1-(2¿-desoxi-2¿, 2¿-difluoro-3¿, 5¿-di-o-benzoil-D-ribofuranosil)-4-aminopirimidin-2-ona con una cantidad catalítica de una alquilamina en presencia de metanol o etanol en un ambiente fundamentalmente exento de agua; tratar la solución resultante con ácido clorhídrico y un antidisolvente; y recuperar el clorhidrato de gemcitabina sólido resultante.This invention provides a process for preparing gemcitabine hydrochloride comprising unblocking β-1- (2¿-deoxy-2¿, 2¿-difluoro-3¿, 5¿-di-o-benzoyl-D-ribofuranosyl) -4- aminopyrimidin-2-one with a catalytic amount of an alkylamine in the presence of methanol or ethanol in an environment essentially free of water; treating the resulting solution with hydrochloric acid and an antisolvent; and recovering the resulting solid gemcitabine hydrochloride.
