4-{3-[4-(2-aminoethyl)phenoxy]propyl}-2-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenol (Preparation 8, 134 mg, 0.27 mmol) and N-{2-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]phenyl}methanesulfonamide (Prepared according to WO2005/080324, 145 mg, 0.28 mmol) were heated at 90° C. in dimethylsulfoxide (0.5 ml) for 24 hours. Ethyl acetate (20 ml) and water (10 ml) were added and the organics separated. The aqueous was washed with ethyl acetate (20 ml) and the combined organics washed with brine (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, 101 mg.
