Procedure

The compound of Example 27 (150 mg, 0.27 mmol) and an excess amount of lithium hydroxide were added to 2 to 3 ml of methanol and about 10 ml of THF. The reaction mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate and washed with water. Chromatography of the reaction mixture on silica gel with 90% ethyl acetate/9.5% methanol/0.5% acetic acid as eluant gave the product.
