Procedure

To a mixture of 5-(aminomethyl)-N-(3-chlorophenyl)-4-(trifluoromethyl)pyrimidin-2-amine (103 mg) and dichloromethane (2 mL) were added tetrahydro-2H-pyran-4-carboxylic acid (53 mg), 1-hydroxybenzotriazole (69 mg), and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (98 mg) in this order at room temperature, and the mixture was stirred at room temperature for 3 days. To the reaction mixture was added ethyl acetate (50 mL), the organic layer was washed with a saturated aqueous sodium hydrogen carbonate solution and saturated brine in this order, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent: chloroform-methanol), and the obtained product was solidified from a mixed solvent of ethanol and ethyl acetate to obtain N-({2-[(3-chlorophenyl)amino]-4-(trifluoromethyl)pyrimidin-5-yl}methyl)tetrahydro-2H-pyran-4-carboxamide (41 mg) as a colorless powder.
