PROCEDURE

实验过程

2.66 g of 3-difluoromethyl-4-(4-methylpiperazin-1-ylmethyl)-N-{4-methyl-3-[4-(5-pyrimidinyl)pyrimidin-2-ylamino]phenyl}benzamide (Example 1) was suspended in 26 ml of ethanol and 4.88 ml of 1 N hydrochloric acid was added thereto, and then the mixture was stirred with heating in a hot bath at 70° C. and dissolved. The solvent was distilled off under reduced pressure, and then the crude crystals were washed with ethanol to obtain 2.80 g of the objective compound.
