实验过程
{(1R)-1-[3,5-bis(benzyloxy)phenyl]-2-bromoethoxy}(tert-butyl)dimethylsilane (Prepared according to US2005/222128, 570 mg, 1.1 mmol), 4-{4-[4-(2-aminoethyl)phenoxy]butyl}-2-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenol bis hydrochloride salt (Preparation 13, 746 mg, 1.3 mmol), sodium hydrogen carbonate (544 mg, 6.48 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 a yellow oil, 720 mg.
