Procedure

Dissolve 3-amino-2-carbethoxy-4,6-dichloroindole (10 g, 36.6 mmol) in anhydrous pyridine (100 mL). Add 4-nitrobenzoyl chloride (7.47 g, 40.27 mmol) and stir for 5 hours. Pour into 1N hydrochloric acid (500 mL) and extract into ethyl acetate. Evaporate the solvent in vacuo and dry at 70° C. under vacuum to give the title compound (15.75 g, 100%); mp 283°-86° c.
