실험 절차

Clopidogrel base was dissolved in methanol. p-Toluene sulphonic acid was added to the solution at 20° C. The reaction mixture was heated to reflux temperature for 2 hrs. The solution was cooled to room temperature and was added drop-wise to diethyl ether. The suspension was stirred at RT. The solid was filtered and dried at about 50° C. in a vacuum oven to give Clopidogrel tosylate similar to that obtained above.
