N-{5-[(1R)-1-{[tert-Butyl(dimethyl)silyl]oxy}-2-{[6-(4-{3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]-4-hydroxyphenyl}butoxy)hexyl]amino}ethyl]-2-hydroxyphenyl}methanesulfonamide (Preparation 28, 420 mg, 0.51 mmol) was dissolved in tetrahydrofuran (6 ml) and triethylaminetrihydrofluoride (415 ul, 2.55 mmol) was added. The reaction was stirred at room temperature for 4 hours and the solvent removed in vacuo, the residue was dissolved in methanol (1 ml) and 880 ammonia (1 ml) and the solvent removed in vacuo, the residue was dissolved in methanol (1 ml) and 880 ammonia (1 ml) and the solvent removed in vacuo. The resulting oil was purified by column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (89/11/1.1 by volume) to furnish the title compound as a yellow solid, 26 mg.
