Procedure

180 mg (0.323 mmol) of the ester from Example 8 and 50 mg (1.29 mmol) of sodium hydroxide are stirred at room temperature in 20 ml of methanol/water 3:1 for minutes, 10 ml of water are added and the mixture is extracted once with dichloromethane. The aqueous phase is acidified using 2 n HCl and extracted twice with dichloromethane. The combined dichloromethane phases are dried over sodium sulphate and evaporated. The residue is recrystallized from diethyl ether.
