Procedure

(5-Bromo-pyrimidin-2-yl)-[2-(cyclopropylmethyl-propyl-amino)-5-trifluoromethyl-benzyl]-amine (2.33 g) is dissolved in N,N-dimethylformamide (16.8 ml) and thereto is added sodium hydride (60%) (273 mg) under ice-cooling. Twenty minutes thereafter, thereto is added 3-bromomethyl-5-trifluoromethyl-benzonitrile (2.08 g) and the mixture is stirred at room temperature for 1 hour and 15 minutes. To the reaction solution are added acetic acid to consume the excess sodium hydride, and thereto are added ethyl acetate and water, and the mixture is separated. The organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure and the resulting residue is purified by silica gel column chromatography (hexane:ethyl acetate=10:1) to give 3-({(5-bromo-pyrimidin-2-yl)-[2-(cyclopropylmethyl-propyl-amino)-5-trifluoromethyl-benzyl]-amino}-methyl)-5-trifluoromethyl-benzonitrile (2.81 g). MS (m/z): 626/628 [M+H]+
