実験手順

N-[(2-chlorophenyl-methyl)]-2-(2-thienyl)ethylamine HCl (28.8 g) is suspended in 75 ml of iso-propanol. 1,3-Dioxane (13.2 g) and 0.25 ml of hydrochloric acid (37% concentration) are added. The reaction mixture is heated to 80° C. for 24 hours. Thereafter, the mixture is cooled to 10° C. and the precipitate is filtered and washed twice with 10 ml of frozen iso-propanol. The product is desiccated at 60° C. UV to yield 24.6 g (82%) Ticlopidine hydrochloride with chemical-physical characteristics as described in Example 1.
