8-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]quinolin-2(1H)-one (Prepared according to WO2005/092861, 530 mg, 1.1 mmol), 4-{4-[4-(2-aminoethyl)phenoxy]butyl}-2-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenol bis hydrochloride salt (Preparation 13, 650 mg, 1.3 mmol), sodium hydrogen carbonate (550 mg, 6.5 mmol) and potassium iodide (50 mg, 0.30 mmol) were added to propionitrile (8 ml) and heated to 90° C. and left to stir overnight. After cooling, ethyl acetate and saturated aqueous sodium hydrogen carbonate were added, organics separated and washed with more saturated aqueous sodium hydrogen carbonate, then brine and then dried (magnesium sulphate) and solvent removed in vacuo. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (100/0/0 to 94/6/0.6 by volume) to furnish the title compound as an oil, 406 mg.
