Reaction Steps

To a solution of 1-(RS and SR)-(cyclohexylamino)-3-(SR)-((4-(N-(benzyloxycarbonyl)-N-(ethyl)amino)piperidin-1-yl)methyl)-4-(SR)-phenylcyclopentane (prepared as in Example 43A) in methylene chloride (2 mL) was added acetic anhydride (0.17 mL, 1.67 mmol) and pyridine (0.17 mL, 2 mmol). The reaction was stirred at rt for 16 h. It was then diluted with methylene chloride and quenched with 1N NaOH. The mixture was washed with 1N NaOH and brine, dried over sodium sulfate and evaporated to dryness. The sample was purified by HPLC and the fractions containing the title compound by HPLC/MS were combined and evaporated.
