Reaction Steps

Ethyl 4-{2-[(3,5-bis-trifluoromethyl-benzyl)-(2-ethylamino-5-trifluoromethyl-benzyl)-amino]-pyrimidin-5-yloxy}-butyrate (200 mg) and pyridine (371 μl) are dissolved in methylene chloride (5 ml), and thereto is added ethyl chlorocarbonate (293 μl) under ice-cooling. The reaction solution is stirred at room temperature overnight and the organic solvent is concentrated under reduced pressure. To the residue are added ethyl acetate and an aqueous citric acid solution, and the mixture is separated. 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 4-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(ethoxycarbonyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yloxy)-butyrate (176 mg). MS (m/z): 725 [M+H]+
