YieldReaction ConditionsOperation in experiment
52.5 g sodium-2-naphthylsulfonate are dissolved in 430 ml dematerialized water under heating at about 75 C. A solution of 50 g Clopidogrel hydrogen sulfate in 200 ml water is added to the solution. The resulting mixture is cooled to room temperature and the upper oily phase is separated. The separated oil is dissolved in 230 g isopropanol. The obtained solution is dried with magnesium sulfate and diluted with 250 g diisopropylether. The solution is inoculated at a temperature of about 60 C. with Clopidogrel napsylate and stirred over night whilst cooling to room temperature. The solid material is isolated by vacuum filtration, washed with diisopropylether and dried under vacuum. 37 g Clopidogrel napsylate of Form A are obtained with the following properties: HPLC content of Clopidogrel napsylate: 100% DSC: endothermic maximum: 149 C.

YieldReaction ConditionsOperation in experiment
In methanol; at 0 - 55℃; for 20h;Heating / reflux;Product distribution / selectivity; Clopidogrel hydrogensulfate, m.p. ~ 184 C (1.78 g) was dissolved inmethanol (25 ml) at a temperature of 55 C and naphthalene 2-sulphonic acid sodium salt (1.15 g) was added. The reaction mixture was vigorously stirred at reflux for 12 hours, and then cooled in a refrigerator for 8 hrs. The reaction mixture was filtered, evaporated to dryness and crystallised from isopropanol. From the cloudy solution the inorganic salt was filtered off and the filtrate was allowed to cool to 0 C. The solid was collected, washed with diethyl ether and dried at 35 C in a vacuum oven for 12 hours to obtain 1.9 g of clopidogrel napsylate.
