실험 절차

A mixture of 2-(cyclohexyl(methoxy)methyl)-5-(trifluoromethyl)benzaldehyde (107 my, 0.36 mmol) and 3,5-bistrifluoromethylbenzylamine (113.8 mg, 0.37 mmol) in ethanol was stirred at room temperature overnight. Sodium borohydride (16.5 mg, 0.44 mmol) was added and the mixture was stirred at room temperature overnight. Solvent was removed and the residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by chromatography over 25+S Biotage silica column (eluted with 0-15% ethyl acetate in heptane) to afford the title compound (150 mg, 80%). 1H NMR (400 MHz, CDCl3) δ ppm 0.94-1.23 (m, 6H) 1.51-1.59 (m, 1H) 1.62 (d, J=7.05 Hz, 2H) 1.69-1.78 (m, 1H) 1.99 (d, J=12.45 Hz, 1H) 3.17 (s, 3H) 3.83 (d, J=12.86 Hz, 1H) 3.92 (d, J=12.86 Hz, 1H) 4.00 (d, J=6.64 Hz, 2H) 4.22 (d, J=7.05 Hz, 1H) 7.50 (d, J=8.30 Hz, 1H) 7.55 (d, J=7.88 Hz, 1H) 7.63 (s, 1H) 7.80 (s, 1H) 7.86 (s, 2H).
