Procedure

To 1 Liter reactor was added Nilotinib-base form A (20 g, 0.04 mol), ethanol absolute (200 ml), and HCl 32% solution in water (6.45 g, 0.04 mol). The slurry was heated to reflux, dissolution occurred during the stirring, and the mixture was filtered under reduced pressure. The Filtrate was fed to second reactor and heated back to reflux. At 76.0° C. the solution was seeded with 0.2 g of dry material obtained by the process of example 23. Precipitation was observed. Then, the solution was maintained at reflux for 0.5 h, followed by cooling for 2 h to 5° C. During cooling at 20° C. ethanol abs. was added (100 ml) and the slurry stirred till reaching to 5° C., filtered, washed with ethanol abs. to yield Nilotinib-HCl form T18.
