10-{4-(Benzyloxy)-3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenyl}dec-9-en-1-amine (Preparation 3, 170 mg, 0.33 mmol) and N-{2-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]phenyl}methanesulfonamide (Prepared according to WO2005/080324, 180 mg, 0.33 mmol) were heated at 90° C. in dimethylsulfoxide (0.5 ml) for 12 hours. Ethyl acetate (20 ml) and water (10 ml) were added and the organics separated, washed with water (10 ml), dried (magnesium sulphate) and the solvent removed in vacuo. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (80/20/2.0 by volume) to furnish the title compound as a glass, 90 mg.
