Participants

Reaction Steps

To a solution of 3-[[[[4′-[3-[(tert-butoxycarbonyl)-[(2R)-2-hydroxy-2-(3-pyridyl)ethyl]amino]propyl]-3-isobutoxy-4-biphenylyl]carbonyl]amino]sulfonyl]propyl acetate (108 mg) in methanol (1.08 ml) and tetrahydrofuran (0.324 ml) was added 1N aqueous sodium hydroxide solution (0.455 ml) and the mixture was stirred at room temperature for 45 minutes. The reaction mixture was concentrated under reduced pressure and the pH value was adjusted to 6.0 with 0.1N hydrochloric acid. The mixture was extracted with ethyl acetate (twice) and the extracts were washed with water and brine, and dried over magnesium sulfate. Filtration followed by evaporation under reduced pressure gave tert-butyl [3-[4′-[[[(3-hydroxypropyl)sulfonyl]amino]carbonyl]-3′-isobutoxy-4-biphenylyl]-propyl][(2R)-2-hydroxy-2-(3-pyridyl)ethyl]carbamate (91.1 mg) as a white solid (foam).
