Procedure

Ethyl (2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-carbamate (980 mg) is dissolved in N,N-dimethylformamide (10 ml), and thereto is added sodium hydride (60%) (91 mg) under ice-cooling, and the mixture is stirred for 30 minutes and thereto is added ethyl iodide (182 μl) and the mixture is stirred at room temperature overnight. Thereto are added water and ethyl acetate, and the mixture is separated, and the organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (hexane:ethyl acetate=19:1→4:1) to give ethyl (2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-bromo-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-ethyl-carbamate (425 mg). MS (m/z): 673/675 [M+H]+
