Ammonium formate → HCID 67097248, compound

Participants

Reaction Steps

The mixture of tert-butyl [(2R)-2-(6-chloro-3-pyridyl)-2-hydroxyethyl][2-[3′-(cyclohexyloxy)-4′-[[[(3-hydroxypropyl)sulfonyl]amino]carbonyl]-4-biphenylyl]-ethyl]carbamate (145 mg), ammonium formate (128 mg) and palladium on carbon powder (50 mg) in methanol (2 ml) and water (0.2 ml) was refluxed for 50 minutes. The catalyst was filtered off and the filtrate was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (chloroform/methanol=94/6) to give tert-butyl [2-[3′-(cyclohexyloxy)-4′-[[[(3-hydroxypropyl)sulfonyl]amino]carbonyl]-4-biphenylyl]ethyl][(2R)-2-hydroxy-2-(3-pyridyl)ethyl]carbamate (117 mg).
