Reaction Steps

A solution of 2-(3-{(2R)-2-[(2R)-2-{[tert-butyl(dimethyl)silyl]oxy}-2-(4-hydroxy-3-hydroxymethyl-phenyl)-ethylamino]-propyl}-phenyl)-N-(2,6-dimethoxybenzyl)-acetamide (Preparation 1) (125 mg, 0.20 mmol) in methanol (6 ml) was treated with acetic acid (6 ml) and ammonium fluoride (74 mg, 2.0 mmol) and the reaction heated to 40° C. for 16 hours. The solvent was removed in vacuo and the residue purified by flash column chromatography on silica gel eluting with dichloromethane:methanol:880 ammonia (95:5:0.5 changing to 93:7:0.7, by volume) to give the title compound as a white solid after trituration with diethyl ether (59 mg).
