Procedure

Dissolve 3-[(phenacyl)carbethoxymethyl-amino]-2-carbethoxy-4,6-dichloroindole (0.29 g, 0.626 mmol) in tetrahydrofuran (27 mL) and water (13 mL). Add lithium hydroxide monohydrate (0.158 g, 3.76 mmol) and stir overnight. Pour into 1N hydrchloric acid (100 mL) and extract into ethyl acetate. Dry (MgSO4) and evaporate the solvent in vacuo. Recrystallize (ethyl acetate/hexane) to give the title compound (0.15 g, mp 235°-7° C.
