Reaction Steps

Tert-butyl 3-[(2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-ethyl-amino]-propionate (which is prepared by treating the corresponding starting compound in a same manner as in Example 12(1)-(4)) (205 mg) is dissolved in a 4N-hydrochloric acid in ethyl acetate (5 ml) and the mixture is stirred at room temperature for 2 hours. To the reaction solution are added a saturated aqueous sodium bicarbonate solution 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=1:1→0:1) to give 3-[(2-{[(3,5-bis-trifluoromethyl-benzyl)-(5-morpholin-4-yl-pyrimidin-2-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-ethyl-amino]-propionic acid (133 mg). MS (m/z): 680 [M+H]+
