Procedure

Compound 19 (18 mg, 0.047 mmol) is dissolved in methanol (0.50 mL) and LiOH (0.04 g, 0.60 mmol) is added. The reaction is heated and maintained at reflux for 2 hours, diluted with ether (5 mL). The organic layer is washed with water (1×5 mL) and brine (1×5 mL). The combined organic layer is concentrated in vacuo then purified by silica gel chromatography eluding with 75% methanol and 25% methylene chloride.
