Procedure

Dissolve 3-[(phenacyl)methylamino]-2-carbethoxy-6-trifluoromethyl-1-(tert-butyloxycarbonyl)indole (200 mg, 0.407 mmol) from above in methylene chloride. Add 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-trifluoromethylindole as a foam (154 mg, 97%).
