A mixture of benzyl 2-[4-((E)-2-methoxycarbonylvinyl)-2,6-dimethylphenyl]-1H-indole-6-carboxylate (950 mg, 2.16 mmol) and 10% palladium on carbon (95 mg) in 100 mL of ethyl acetate/ethanol (1:1) was stirred under a hydrogen balloon for 18 h. The mixture was filtered through Celite to remove catalyst, and the solvent removed under reduced pressure to leave 2-[4-(2-methoxycarbonylethyl)-2,6-dimethylphenyl]-1H-indole-6-carboxylic acid. MS (m/z) 352.2 (M+1): Retention time=1.35 min (Method 10).
