Reaction Steps

(3R)-3-[5-{2-[4-(2-aminoethyl)phenoxy]ethyl}-2-(benzyloxy)phenyl]-N,N-diisopropyl-3-phenylpropan-1-amine bis hydrochloride salt (Preparation 42, 800 mg, 1.25 mmol), 8-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]quinolin-2(1H)-one (Prepared according to WO2005/092861, 615 mg, 1.25 mmol), potassium iodide (210 mg, 1.25 mmol), sodium hydrogen carbonate (630 mg, 7.5 mmol) were added to propionitrile (15 ml) and stirred at 100° C. under nitrogen overnight. The mixture was cooled and water (100 ml) and ethyl acetate (100 ml) added. Organics were separated and washed with water (100 ml) then brine (50 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 (100/0/0 to 90/10/1 by volume) to furnish the title compound as a gum, 297 mg.
