Reaction Steps

132 (160 mg, 0.569 mmol) is dissolved in 5 ml of methanol and treated with a solution of LiOH (27.2 mg, 1.138 mmol) in 3 ml of water. The mixture is stirred at room temperature overnight. Since the reaction is not complete (TLC), additional LiOH (30 mg, 1.25 mmol) is added and the stirring is continued for additional 18 h. After evaporation, the crude product is acidified at 0° C. with 2M HCl and extracted with ethyl acetate. The organic layers are dried over sodium sulphate and evaporated.
