To a solution of 2-[2-[2-(3,5-dimethylphenyl)-5-hydroxy-1H-indol-3-yl]ethyl]isoindole-1,3-dione (418 mg in a mixture of 7 mL ethanol and 7 mL tetrahydrofuran) was added 2.5 mL of 95% aqueous hydrazine and the reaction stirred at room temperature. After 12 hours the mixture was concentrated in vacuo and purified by flash chromatography on silica gel (methylene chloride:methanol:ammonium hydroxide, 89:11:1) to provide the title compound (228 mg).
