実験手順: To a stirring ice-cold solution of 14 (10.0 g, 34.09 mmol) and Et3N (14.2 mL, 102.27 mmol) in CH2Cl2 (200 mL) was slowly added 1-cyclopropylmethylsulfonyl chloride (5.27 g, 34.09 mmol). The mixture stirred at ambient temperature under an atmosphere of nitrogen for 3 h. The mixture was washed with 2 N NaOH (50 mL), 2 N HCl (50 mL), H2O (50 mL), brine (50 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure to afford N-((1-(4-(cyclopropylmethylsulfonyl)piperazin-1-yl)cyclohexyl)methyl)-2,2,2-trifluoroacetamide (18) as an off-white solid (14.00 g, quantitative): MS (ESI+) m/z 412. The mixture was washed with 2 N NaOH (50 mL), 2 N HCl (50 mL), H2O (50 mL), brine (50 mL) dried (Na2SO4) filtered concentrated under reduced pressure

実験手順: tert-Butyl 7-(aminomethyl)-1-benzyl-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (0.600 g, 1.637 mmol) was suspended in dichloromethane (5 mL) and triethylamine (0.228 mL, 1.637 mmol) and cooled to 0° C. Cyclopropylmethanesulfonyl chloride (0.253 g, 1.637 mmol) was added. The solid immediately dissolved. The mixture was stirred overnight and then diluted with dichloromethane and washed with brine (3×50 mL). The organic extract was collected dried on MgSO4 and evaporated under reduced pressure. The residue was purified by flash-chromatography on silica gel (100% dichloromethane 5 minutes then gradient to 1% MeOH in dichloromethane). Product was isolated as white powder (601.9 mg, 1.24 mmol, 76%). The solid immediately dissolved washed with brine (3×50 mL) The organic extract was collected dried on MgSO4 evaporated under reduced pressure The residue was purified by flash-chromatography on silica gel (100% dichloromethane 5 minutes
