Procedure

To a solution of 2-(5-{3-[4-(4-Chloro-phenyl)-4-hydroxy-3,3-dimethyl-piperidin-1-yl]-propylidene}-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yloxy)-2-methyl-propionic acid ethyl ester (158 mg, 0.261 mmol) in methanol (3 mL) was added sodium hydroxide (1 N in water, 1 mL). Following a slight exotherm, the mixture clarified. An additional aliquot of sodium hydroxide (1 N, 1 mL) was added after 1 h and the mixture was allowed to stir an additional 1 h at rt. The solvents were evaporated under reduced pressure and the residue dissolved in water (2.5 mL). The basic solution was neutralized (pH=7) with hydrochloric acid (1 N) and the titled compound was precipitated and collected by suction filtration (86 mg, 57%).
