To a mixture of N-adamantan-1-yl-5-(chloromethyl)-4-(trifluoromethyl)pyrimidin-2-amine (170 mg) and N,N-dimethyl formamide (4 mL) were added morpholine (0.21 mL) and potassium carbonate (136 mg) under ice-cooling, and the mixture was stirred at room temperature for 1.5 hours. To the reaction mixture was added water, and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate) to obtain N-adamantan-1-yl-5-(morpholin-4-ylmethyl)-4-(trifluoromethyl)pyrimidin-2-amine (160 mg) as a white solid.
