실험 절차

To a solution of 2-(trimethylsilyl)ethyl 3-(1-hydroxycyclohexyl)-2-aminopropylmethylcarbamate (18.3 mg, 0.055 mmol) in CH2Cl2 (2 mL) was added Et3N (0.2 mL) and TMSCl (12 mg, 14 μL, 0.11 mmol). The resulting solution was stirred for 1 h and evaporated under vacuum. The residue was dissolved in CH2Cl2 (2 mL) and pyridine (0.05 mL) was added, followed by 4-nitrophenyl chloroformate (13.5 mg, 0.66 mmol). The solution was stirred for 30 min and (S)-1-(3-fluorophenyl)-5-methoxy-1-((R)-piperidin-3-yl)pentan-1-ol hydrochloride (18 mg, 0.055 mmol). The resulting mixture was stirred for 10 min and evaporated. The residue was purified by prep HPLC to give (3R)-3-((S)-1-(3-fluorophenyl)-1-hydroxy-5-methoxypentyl)-N-(3-(1-hydroxycyclohexyl)-1-(N-methyl-N-(2-(trimethylsilyl)ethoxycarbonyl)amino)propan-2-yl)piperidine-1-carboxamide (17.8 mg, 50%). MS m/z 652 (M+H+).
