Procedure

A mixture of 4-[3-(3-nitrobenzoyl)indol-1-yl]butyric acid (1.20 g), 10% palladium on carbon (300 mg), methanol (12 ml) and 1,4-dioxane (12 ml) was stirred under hydrogen atmosphere (3 atm) at 25° C. for 45 minutes. The mixture was filtered and the filtrate was evaporated to give 4-[3-(3-aminobenzoyl)indol-1-yl]butyric acid (982 mg) as yellow oil.
