実験手順
To a solution of benzyl 4-[5-chloro-1-(3-nitrobenzoyl)indol-3-yl]butyrate (1.3 g) in a mixture of methanol (35 ml), 1,4-dioxane (35 ml) and water (5 ml) was added 10% palladium on activated carbon (400 mg), and the mixture was stirred under hydrogen atmosphere (3 atm) at 20° C. for 4 hours. The catalyst was filtered off and the filtrate was evaporated. The residue was chromatographed on silica gel (40 g) eluting with 2% methanol in chloroform to give 4-[1-(3-aminobenzoyl)-5-chloroindol-3-yl]butyric acid (731 mg) as pale yellow crystals.
