実験手順

3-Bromo-N-[(2S)-2-(4-fluorophenyl)-4-oxobutyl]-N-methyl-5-(trifluoromethyl)benzamide (see method 1; 1.00 g, 2.24 mmol) and 1-azetidin-3-ylpiperidine-4-carboxamide (see method 4; 0.49 g, 2.69 mmol) and triethylamine (1.24 mL, 9.0 mmol) were dissolved in methylene chloride (30 mL) together with methanol (5 mL). To the resultant solution was added sodium cyanoborohydride (0.21 g, 3.36 mmol) and the mixture was stirred at RT for 20 min. The solvent was removed by evaporation and the residue was partitioned between methylene chloride and saturated aqueous NaHCO3. The organic phase was filtered through a phase separator and the solvent was removed by evaporation. The product was purified by chromatography on silica gel (ammonia saturated methanol/methylene chloride, 1-20% methanol). There was obtained 0.24 g (17%) of the title compound. 1H NMR (500 MHz, CDCl3): δ 1.4-3.8 (cm, 23H), 5.7 (b, 1H), 5.8 (b, 1H), 6.8-7.4 (cm, 6H), 7.7 (s, 1H); LCMS: m/z 614 (M+1)+.
