Reaction Steps

Mix 3-[(phenacyl)ethylamino]-2-carbethoxy-4,6-dichloroindole (600 mg, 1.48 mmol), water (10 mL) and tetrahydrofuran (10 mL). Add lithium hydroxide monohydrate (0.22 g, 5.18 mmol) and stir at room temperature for 24 hours.Heat to reflux for 5 hours then pour into 1N hydrochloric acid (100 mL). Extract into ethyl acetate, dry (MgSO4) and evaporate the solvent in vacuo to give the crude product (0.72 g) as a white solid. Recrystallize (ethyl acetate/hexane) to give the title compound (0.32 g, 57%); mp 254°-6° C.
