실험 절차

To a solution of (S)-1-(3-chloro-2-fluorophenyl)-5-methoxy-1-((R)-piperidin-3-yl)pentan-1-ol (33.0 mg, 0.10 mmol) in CH2Cl2 (2 mL), DIEA (39 mg, 0.30 mmol) was added, followed by the solution of 2-(trimethylsilyl)ethyl (2S,3S)-3-(4-nitrophenoxycarbonylamino)-4-cyclohexyl-2-(trimethylsilyloxy)butylcarbamate in CH2Cl2 (0.8 mL, 0.2 mmol) prepared in the previous step. The resulting yellow solution was stirred at rt for 30 min, and completion of reaction was confirmed by LC-MS. Solvent was removed under vacuum, and the residue was purified by preparative HPLC to give 2-(trimethylsilyl)ethyl (2S,3S)-3-((R)-3-((S)-1-(3-chloro-2-fluorophenyl)-1-hydroxy-5-methoxypentyl)piperidine-1-carboxamido)-4-cyclohexyl-2-hydroxybutylcarbamate (25.8 mg, 38%); MS m/z 686 (M+H+).
