N-[2-(benzyloxy)-5-{(1R)-1-{[tert-butyl(dimethyl)silyl]oxy}-2-[(8-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenyl}octyl)amino]ethyl}phenyl]methanesulfonamide (Preparation 54, 90 mg, 0.10 mmol), ammonium formate (130 mg, 2.0 mmol) and 20% palladium hydroxide on carbon (20 mg) were mixed in ethanol (3 ml) and heated to 70° C. overnight. Reaction mixture was then cooled and filtered. The filtrate was collected and the solvent removed in vacuo. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (98/2/0.2 to 91/9/0.9 by volume) to furnish the title compound as a gum to furnish the title compound as a glass, 82 mg.
