Reaction Conditions

Reaction Steps

To a solution of the ester of Example 6 in THF (0.8 mL) was added a solution of KOH (14 mg, 0.255 mmol) in H2O (0.2 mL). The mixture was stirred at 50° C., then concentrated to remove THF. The aqueous phase was washed with ethyl ether, then the aqueous phase was acidified until pH 3–4 was reached. The acidified solution was extracted with Et2O or EtOAc (3×), dried over MgSO4, filtered and concentrated in vacuo to give a white solid.
