Versuchsvorschrift

N-(5-{(1R)-1-{[tert-butyl(dimethyl)silyl]oxy}-2-[(8-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenyl}octyl)amino]ethyl}-2-hydroxyphenyl)methanesulfonamide (Preparation 55, 74 mg, 0.095 mmol) was dissolved in tetrahydrofuran (3 ml) and triethylaminetrihydrofluoride (90 ul, 0.54 mmol) was added in one portion at room temperature. The reaction was stirred for 12 hours and the solvent removed under reduced pressure, the residue was dissolved in methanol (10 ml) and 880 ammonia (1 ml) and the solvent removed under reduced pressure. The residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (97/3/0.3 to 85/15/1.5 by volume) to furnish the title compound as a yellow solid, 34 mg.
