Reaction Conditions

Reaction Steps

Nilotinib base form A (0.5 g, 0.94 mmol) was suspended in ethanol absolute (4 ml), then an HCl solution (0.23 mL, 19.48% in IPA) was added and the reaction mixture became yellow. The slurry was stirred at room temperature (20-30° C.) for 16 h. The product was filtered and washed twice with ethanol absolute (1.5 ml). The solid was dried under vacuum oven at 50° C. overnight to yield Nilotinib HCl form T2.
