PROCEDURE
实验过程
4-{4-[4-(2-aminoethyl)phenoxy]butyl}-2-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenol tert-butyl{2-[4-(4-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenyl}butoxy)phenyl]ethyl}carbamate bis hydrochloride salt (Preparation 13, 1.30 g, 2.26 mmol), was dissolved in a mixture of saturated aqueous sodium hydrogen carbonate and dichloromethane. The organic layer was separated, dried (magnesium sulphate) and the solvent removed in vacuo The residue was dissolved in acetonitrile (10 ml) and {2-(benzyloxy)-5-[(1R)-2-bromo-1-{[tert-butyl(dimethyl)silyl]oxy}ethyl]phenyl}methanol (Prepared according to WO2004/032921, 1.02 mg, 2.26 mmol), sodium hydrogen carbonate (570 mg, 6.78 mmol) were added, and heated to 85° C. and stirred overnight. After cooling the solvent was removed in vacuo and the residue was dissolved in dichloromethane (30 ml) and washed with water (2×20 ml) then brine (20 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 (95/5/1 to 90/10/1 by volume) to furnish the title compound as a gum, 388 mg.
