Procedure

81.5 mg (1.94 mmol) of lithium hydroxide monohydrate are added to a solution of 370 mg (0.647 mmol) of methyl 4-[(4E)-3-[4-(methoxycarbonyl)benzyl]-5-{2-[3-(2-oxo-1,3-oxazolidin-3-yl)-propoxy]phenyl}pent-4-en-1-yl]benzoate (Example 26A) in 2 ml of THF and 2 ml of water, and the mixture is stirred at room temperature for 18 h. The mixture is then adjusted to pH 2 using 1 M hydrochloric acid and extracted twice with ethyl acetate. The combined organic phases are dried over sodium sulfate. After filtration, the solvent is removed to dryness and the crude product is purified by preparative HPLC. This gives 114 mg (0.210 mmol, 32.4% of theory) of the title compound as a colorless solid.
