PROCEDURE

实验过程

A suspension of 10 (270 mg, 0.28 mmol) in a mixture of THF (6 ml), MeOH (4 ml) and 4M LiOH (2 ml) was stirred at 55° C. for 30 h. The reaction was cooled and neutralized to pH 6 with cold 10% citric acid. Insoluble material was collected by filtration and washed with water, MeOH and ether. Drying under vacuum afforded 160 mg (60%) of the title compound 11. By HPLC analysis this product contained ˜5% of unreacted 10. The crude acid was used in the next step without additional purification.
