実験手順

0.10 g palladium (5% on activated charcoal) were added to. a solution of 0.30 g (0.41 mmol) (R)—N-(2-benzyloxy-5-{2-[1,1-dimethyl-3-(4-phenylimidazol-1-yl)-propylamino]-1-hydroxyethyl)phenyl)-benzenesulphonamide in 15 mL ethanol. The reaction mixture was shaken in an autoclave under a hydrogen pressure of 20 psi at ambient temperature for 3 h. The hydrogen pressure was released, the palladium was filtered off and the filtrate was freed from solvent using the rotary evaporator. The residue was purified by flash column chromatography [methylene chloride/methanol/ammonia (90:10:1)]. 0.20 g (0.31 mmol, 75%) (R)—N-(5-{2-[1,1-dimethyl-3-(4-phenylimidazol-1-yl)-propylamino]-1-hydroxyethyl}-2-hydroxy-phenyl)-benzenesulphonamide was obtained as a colourless solid.
