実験手順

Dissolve 3-[(phenylsulfonyl)methylamino]-2-carbethoxy-4,6-dichloro-tert-butyloxycarbonyl-indole (400 mg, 0.758 mmol) in methylene chloride (15 mL). Add, by dropwise addition, trifluoroacetic acid (15 mL) and stir at room temperature for 3 hours. Evaporate the solvent in vacuo and treat the resulting residue with saturated sodium hydrogen carbonate. Extract into methylene chloride and dry (MgSO4). Recrystallize (ethyl acetate/hexane) to give the title compound (70 mg, 22%); mp 244°-45° C.
