Procedure

Dissolve 3-[(phenacyl)methylamino]-2-carbethoxy- 6-nitro-1-(tert-butyloxycarbonyl)-indole from above in methylene chloride. Add excess trifluoracetic acid and stir overnight at room temperture. Concentrate the reaction in vacuo, dilute with ethyl acetate and rinse with saturated sodium bicarbonate, dry over magnesium sulfate, filter and concentrate in vacuo to yield 3-[(phenacyl)methylamino]-2-carbethoxy-6-nitroindole.
