Procedure

Tert-butyl[2-(4-{[(4E)-5-{4-(benzyloxy)-3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenyl}pent-4-en-1-yl]oxy}phenyl)ethyl]carbamate (Preparation 57, 2.5 g, 3.5 mmol) was dissolved in ethanol (50 ml) and palladium hydroxide (20% by weight on carbon, 600 mg, 0.84 mmol) and ammonium formate (2.0 g, 30 mmol) were added and stirred at 90° C. for 1 hour. Reaction was cooled and filtered through arbocel and the solvent removed in vacuo. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (95/5/0.5 to 90/10/1 by volume) to furnish the title compound as a white foam, 1.66 g
