Reaction Steps

Sertraline mandelate (20 g) and n-butanol were stirred at room temperature. The mixture was acidified with hydrogen chloride until pH 0 was reached. During the acidification the temperature of the reaction mixture rose to ˜50° C. After the natural cooling to room temperature, the mixture was stirred at room temperature for two hours. The solid was filtrated, washed with n-butanol and dried at 80° C. to afford sertraline hydrochloride Form II (9.02 g).
