Procedure

Dissolve 3-[(phenacyl)methylamino]-2-carbethoxy-5,6-dichloro-1-(tert-butyloxycarbonyl)-indole from above in methylene chloride (15 mL). Add trifluoracetic acid (5 mL) and stir for 5 hours. Concentrate the reaction in vacuo, dilute with ethyl acetate (100 mL), wash with saturated sodium carbonate, dry over magnesium sulfate, filter and concentrate in vacuo. Recrystallize the residue from ethyl acetate/hexane to yield the title compound.
