1,3-Dioxolane → Ticlopidine Hydrochloride

참여 물질

반응 단계

N-[(2-chlorophenyl-methyl)]-2-(2-thienyl)ethylamine HCl (28.8 g) is suspended in 75 ml of 1,3-dioxolane. Hydrochloric acid at 37% concentration (0.25 ml) is added and the temperature of the reaction mixture is brought to 80° C. for 5 hours. Thereafter the reaction is complete. The mixture is cooled to room temperature, and the compound precipitates out. To complete the precipitation and simplify filtration, 75 ml of ethyl acetate is added to the reaction mixture. The filter cake is washed with ethyl acetate (2×20 ml) and dried at 60° C. UV. Ticlopidine HCl (28.5 g, 95% yield) is obtained with m.p. 208-210° C.
