Reaction Steps

A mixture of ethyl 4-[5-chloro-3-(3-nitrobenzoyl)indol-1-yl]butyrate (2.00 g), 1N aqueous sodium hydroxide (7.5 ml), methanol (35 ml) and 1,4-dioxane (35 ml) was stirred at 25° C. for 6 hours. After evaporation of the organic solvent, 1N hydrochloric acid (15 ml) was added to the aqueous solution and the mixture was extracted with ethyl acetate. The extract was washed with water, dried over magnesium sulfate, and evaporated in vacuo. The crystalline residue was washed with hot ethanol to give 4-[5-chloro-3-(3-nitrobenzoyl)indol-1-yl]butyric acid (1.77 g) as colorless crystals.
