実験手順: The mixture of 1-(7,8-dihydro-naphthalen-1-yl)-ethanone (10) (172 mg, 1.0 mmol) and 3-(3-trifluoromethyl-phenyl)-propylamine (13) (204 mg, 1.0 mmol) in titanium (IV) isopropoxide (1 mL) was stirred at room temperature overnight. Methanol(5 mL) was added followed by addition of sodium borohydride (55 mg, 2.0 mmol). The reaction mixture was stirred at room temperature for 1 hour and evaporated to dryness. The crude product was purified by chromatography on silica gel, loaded with dichloromethane and eluted with 2% methanol in dichloromethane containing 0.5% ammonium hydroxide. The pure fractions were combined and evaporated to give a colorless oil. The product was converted to a hydrochloride salt by addition of 1 N HCl in ethyl ether. Evaporation gave compound (1) as an off-white solid (325 mg, 82.2%). The reaction mixture was stirred at room temperature for 1 hour evaporated to dryness The crude product was purified by chromatography on silica gel eluted with 2% methanol in dichloromethane containing 0.5% ammonium hydroxide evaporated to give a colorless oil Evaporation
