Procedure

1.98 g of 4-methyl-3-[4-(5-pyrimidinyl)pyrimidin-2-ylamino]aniline (Reference Example 18) was dissolved in 35 ml of anhydrous pyridine and 2.90 g of 3-difluoromethyl-4-(4-methylpiperazin-1-ylmethyl)benzoyl chloride hydrochloride (Reference Example 9) was added, followed by stirring at room temperature for 2 hours. To the reaction solution, ice water and an aqueous saturated sodium hydrogen carbonate solution were added and then the mixture was subjected to extraction with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The crude crystals were washed with chloroform-diethyl ether (1:1) to obtain 2.66 g of the objective compound as pale brown crystals.
