To a solution of the above ester (239 mg, 0.488 mmol) in methanol (40 ml) was added 1N NaOH (0.975 ml, 0.975 mmol) and the mixture were refluxed for 2 hr. After cooling to room temperature the mixture were evaporated in vacuo. The residue was dissolved in dichloromethane (50 mL) and extracted with water (10 ml). The aqueous phase was acidified with 1N HCl (1 ml) pH 3 and extracted with dichloromethane (20 ml). The dichloromethane phase were dried with anhydrous magnesium sulfate and subsequently evaporated in vacuo yielding the title acid as light green foam.
