Reaction Steps

A mixture of ethyl 2-((R)-1-(3-chlorophenyl)-1-((R)-1-((S)-1-cyclohexyl-3-(methyl((2-(trimethylsilyl)ethoxy)carbonyl)amino)propan-2-ylcarbamoyl)piperidin-3-yl)ethoxy)acetate (0.0185 g) and 33% wt. methylamine in ethyl alcohol (10 mL) was stirred at rt for 3 d. After the reaction mixture was evaporated under reduced pressure, the crude product was purified by reversed-phase HPLC to afford 0.0035 g of 2-(trimethylsilyl)ethyl (S)-2-((R)-3-((R)-1-(3-chlorophenyl)-1-(2-(methylamino)-2-oxoethoxy)ethyl)piperidine-1-carboxamido)-3-cyclohexylpropyl(methyl)carbamate. MS ESI +ve m/z 653 (M+H).
