Reaction Steps
Dissolve 3-[(phenacyl)benzylamino]-2-carbethoxy-2,6-dichloro-1-tert-butyloxycarbonyl-indole (0.68 g, 1.26 mmol) in methylene chloride (5 mL) and add, by dropwise addition, trifluoroacetic acid (5 mL). Stir for 4 hours then slowly add to saturated sodium hydrogen carbonate (100 mL). Extract into methylene chloride, dry (MgSO4) and evaporate the solvent in vacuo. Recrystallize (ethyl acetate/hexane) to give the title compound (0.34 g, 59%); mp 174°-5° C.
