N-{5-((1R)-1-Hydroxy-2-{[(1S)-2-hydroxy-1-phenylethyl]amino}ethyl)-2-[(phenylmethyl)oxy]phenyl}-N-(phenylmethyl)methanesulfonamide → (R)-N-(5-(2-amino-1-hydroxyethyl)-2-hydroxyphenyl)methanesulfonamide

Participants

Reaction Steps

To an evacuated flask containing palladium hydroxide (70.8 mg) and palladium on carbon [50% water by weight] (70.8 mg) was added a solution of N-{5-((1R)-1-hydroxy-2-{[(1S)-2-hydroxy-1-phenylethyl]amino}ethyl)-2-[(phenylmethyl)oxy]phenyl}-N-(phenylmethyl)methanesulfonamide (354 mg) in EtOH (15 ml) and AcOH (3 ml). The mixture was hydrogenated for 19 h. The catalysts were filtered off and the filtrate concentrated in vacuo. The mixture was purified by column chromatography (Oasis cartridge, 0 to 50% MeOH in water) to afford the title compound. LCMS RT=0.35 min
