Procedure

A solution of 2-chloro-4-methylamino-pyrimidine-5-carbaldehyde (1.08 g, 6.3 mmol) and N-(3-amino-4-methyl-phenyl)-3-trifluoromethylbenzamide (2.04 g, 6.9 mmol) in MeOH (70 mL) is stirred for 2 hours at 45° C. and then treated with sodium cyanoborohydride (1.19 g, 18.9 mmol) and acetic acid (1 mL) sequentially. After stirring for 2 hours at room temperature, the reaction mixture is diluted with CHCl3 and washed with saturated NaHCO3. The organic layer is dried over MgSO4 and concentrated under reduced pressure. The residue is purified by flash column chromatography (SiO2, EtOAc/hexane=1/2) to give N-{3-[(2-chloro-4-methylaminopyrimidin-5-ylmethyl)amino]-4-methylphenyl}-3-trifluoromethylbenzamide (1.80 g, 64%) as a white solid.
