実験手順

tert-butyl[2-(4-hydroxyphenyl)ethyl]carbamate (Prepared according to WO1998/43942, 3.8 g, 7.3 mmol), potassium carbonate (2.6 g, 8.0 mmol), potassium iodide (1.1 g, 7.3 mmol) and 2-{4-(benzyloxy)-3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenyl}ethyl methanesulfonate (preparation 36, 1.56 g, 2.98 mmol) were stirred in toluene (20 ml) and stirred at 120° C. overnight. After cooling, water (80 ml) and ethyl acetate (80 ml) were added, organics separated and washed with saturated aqueous sodium hydrogen carbonate (40 ml), brine (40 ml) then 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 90/10/1.0 by volume) to furnish the title compound as an oil, 3.4 g.
