Procedure

A solution of the above ester from Example 11D in MeOH (4 mL) and 4N KOH (1.3 mL) was stirred at room temperature for 18 hours. MeOH was removed, the residue was treated with water, and the solution was adjusted to pH 5. It was extracted with EtOAc and the extract was dried and evaporated to give a pale yellow solid which was used as is for condensation with oxindole.
