A mixture of 4-[1-(3-aminobenzoyl)-5-chloroindol-3-yl]butyric acid (700 mg), bis(4-isobutylphenyl)methyl bromide (705 mg) and diisopropylethylamine (620 mg) in dichloromethane (20 ml) was stirred at 20° C. for 1 hour, and then bis(4-isobutylphenyl)methyl bromide (150 mg) and diisopropylethylamine (70 mg) were added. After stirred at 20° C. for 3 hours, the reaction mixture was poured into iced 1N hydrochloric acid. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. After evaporation of the solvent, the residue was chromatographed on silica gel (20 g) eluting with a mixture of hexane and ethyl acetate (10:1 to 1:1) to give 4-[1-[3-[bis(4-isobutylphenyl)methylamino]benzoyl]-5-chloroindol-3-yl]butyric acid (803 mg).
