Procedure

N-{2-(benzyloxy)-5-[(1R)-1-{[tert-butyl(dimethyl)silyl]oxy}-2-({2-[4-(4-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenyl}butoxy)phenyl]ethyl}amino)ethyl]phenyl}formamide (Preparation 29, 400 mg, 0.45 mmol), ammonium formate (570 mg, 9.0 mmol) and 20% palladium hydroxide on carbon (60 mg) were mixed in methanol (8 ml) and stirred at 70° C. for 1 hour under nitrogen. Further ammonium formate (500 mg, 7.9 mmol) and 20% palladium hydroxide on carbon (50 mg) were then added and heating continued at 70° C. for further 1 hour. Reaction mixture was then cooled and filtered, the filtrate was collected and the solvent removed in vacuo. The residue was dissolved in methanol (8 ml) and ammonium formate (500 mg, 7.9 mmol) and 20% palladium hydroxide on carbon (50 mg) were added and stirred at 70° C. for 1 hour under nitrogen. Reaction mixture was then cooled and filtered, the filtrate was collected and the solvent removed in vacuo. The residue was dissolved in ethyl actate (25 ml) and saturated aqueous sodium hydrogen carbonate (25 ml). Organics were separated and washed with brine (15 ml), dried (magnesium sulphate) and solvent was removed in vacuo to furnish the title compound as a yellow solid, 280 mg.
