Succinic Acid → Nilotinib succinate

Participants

Reaction Conditions

Reaction Steps

Nilotinib base (0.300 g, 0.57 mmol) was dissolved in TFE (2 mL) at 40° C. to obtain a mixture. The mixture was stirred and added to a solution of succinic acid (0.066 g, 0.57 mmol) in TFE (1 mL) at 40° C. The resulting solution was stirred for about 4 h and subsequently cooled to 5° C. The mixture was kept at 5° C. overnight and then a sample (1 mL) was taken from the mixture and evaporated to dryness under reduced pressure at 40° C. to give Nilotinib succinate form II.
