To a stirred solution of ethylcarbamic acid 3-(2-[benzyloxycarbonyl-[4-(4-benzyloxyphenyl)butyl]amino]-ethyl)-2-(3,5-dimethylphenyl)-1H-indol-5-yl ester (12 mg in a mixture of 1.5 mL tetrahydrofuran and 0.5 mL methanol) was added 12 mg of 10% palladium hydroxide on carbon catalyst followed by acetic acid (0.010 mL of a 30% solution in water). The reaction flask was fitted with a hydrogen balloon, evacuated and recharged with hydrogen (3 times) and stirred at room temperature. After 1.5 hours the reaction was flushed with nitrogen, filtered over diatomaceous earth and concentrated in vacuo. Purification by flash chromatography (methylene chloride:methanol: ammonium hydroxide, 90:7:1) gave the title compound (8.2 mg). m/e=500 (M+H)
