Procedure

8-(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]quinolin-2(1H)-one (Preparation 31, 406 mg, 0.45 mmol), ammonium formate (560 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 (300 mg, 4.8 mmol) and 20% palladium hydroxide on carbon (30 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 (560 mg, 8.9 mmol) and 20% palladium hydroxide on carbon (60 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. Residue was dissolved in ethyl acetate (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, 305 mg.
