실험 절차
Nilotinib base Form A (4.00 g, 7.55 mmol) was mixed with dimethylformamide (“DMF”) (40 mL, 10V) to obtain a suspension. The suspension was heated to 80° C. and stirred at the same temperature for 30 min to produce a clear yellow solution. To the solution was added a solution of L-tartaric acid (1.25 g, 8.31 mmol, 1.1 mol eq) in DMF (4 mL, 1V) in one portion. The solution was stirred at 80° C. for 1 hour. Then the heating source was removed and the mixture was allowed to cool to room temperature. The stirring was continued at ambient temperature over a period of 6 h after which time the mixture was transferred to the refrigerator for 16 h. MTBE (400 mL) was added portion-wise to the mixture at room temperature until a light yellow precipitate was formed. The resulting suspension was stirred at room temperature for 6 h and then filtered to give Nilotinib L-tartrate form V as a light-yellow solid.
