Procedure

N-{2-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]phenyl}formamide (Prepared according to US2005/215590, 440 mg, 0.95 mmol) (3R)-3-[5-{2-[4-(2-aminoethyl)phenoxy]ethyl}-2-(benzyloxy)phenyl]-N,N-diisopropyl-3-phenylpropan-1-amine bis hydrochloride salt (Preparation 42, 600 mg, 0.95 mmol) potassium iodide (160 mg, 0.94 mmol), sodium hydrogen carbonate (480 mg, 5.65 mmol) were added to propionitrile (10 ml) and stirred at 100° C. under nitrogen for 24 hours. The mixture was cooled and water (75 ml) and ethyl acetate (75 ml) were added. Organics were separated and washed with brine, 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 (99/1/0.1 to 90/10/1 by volume) to furnish the title compound as a gum, 174 mg.
