PROCEDURE

实验过程

A mixture of crude 2-(trimethylsilyl)ethyl (2S)-2-((3R)-3-((1R)-(2-aminopropoxy)(3-chlorophenyl)methyl)piperidine-1-carboxamido)-3-cyclohexylpropyl(methyl)carbamate (0.1340 g), obtained as, described above, DMAP (0.151 g), DIPEA (2 mL), and methyl chloroformate (0.483 g) in CH2Cl2 was stirred at rt for 2 d. After the reaction mixture was evaporated under reduced pressure, the crude product was purified by reversed-phase HPLC to give 2-(trimethylsilyl)ethyl (S)-2-((R)-3-((R)-(2-(methoxycarbonylamino)propoxy)(3-chlorophenyl)methyl)piperidine-1-carboxamido)-3-cyclohexylpropyl(methyl)carbamate. MS ESI +ve m/z 705 (M+Na).
