Procedure

To a solution of 1-[3-(7-(2-acetoxyethyl)oxy-5,11-dihydro[1]benzoxepino[2,3-b]pyridin-5-ylidene)propyl]-4-(4-chlorophenyl)piperidin-4-ol (Example 50) (140 mg) in ethanol (5 ml) were added 15% sodium hydroxide aqueous solution (2 ml) and the mixture was heated to reflux for 1 hour. Water and ethyl acetate were added to the reaction mixture, the organic layer was separated and washed with saturated aqueous sodium chloride, and dried with magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography eluting with methylene chloride-methanol (10:1) to give the titled compound (120 mg).
