Procedure

Erlotinib trifluoroacetate salt (10 g) was charged in to isopropyl alcohol (60 ml) at 25° C. to 30° C. 7.5% isopropanolic hydrochloride (13 ml) was added slowly to the reaction mixture at 25° C. to 30° C. and stirred for about 2 hours at 25° C. to 30° C. The solid obtained was filtered, washed with DI water (2×15 ml), suck dried and dried under vacuum for about 18 hours at 40° C. to 45° C. to give erlotinib hydrochloride.
