Procedure

The compound of Example 34 (70 mg, 0.14 mmol) and excess 1.0M lithium hydroxide solution were added to about 2 ml of methanol and about 1 ml of THF. The reaction mixture was stirred at room temperature overnight and then diluted with ethyl acetate and washed with water. Chromatography of the reaction mixture on silica gel with 90% ethyl acetate/10% methanol/trace amount of acetic acid as eluant gave the product.
