Reaction Steps
136 (520 mg, 1.761 mmol) is dissolved in 10 ml of methanol and treated with a solution of LiOH (84.3 mg, 3.52 mmol) in 5 ml of water. The mixture is stirred at room temperature for 18 hours. 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.
