Procedure

N-(5-{(1R)-1-{[tert-butyl(dimethyl)silyl]oxy}-2-[(7-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenoxy}heptyl)amino]ethyl}-2-hydroxyphenyl)methanesulfonamide (Preparation 20, 68 mg, 0.087 mmol) was dissolved in tetrahydrofuran (3 ml) and N,N-diethylethanamine trihydrofluoride (71 μl, 0.43 mmol) was added dropwise. After 18 hours a mixture of methanol (4 ml) and 880 ammonia (8 ml) were added and after 15 minutes the solvent was removed in vacuo. The residue was dissolved in dichloromethane and the solvent removed in vacuo again and the residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (97/310.3 to 88/12/1.2 by volume) to furnish the title compound as a white solid, 30 mg.
