Reaction Conditions

Reaction Steps

A mixture of 3-[3-[2,2-bis(4-isobutylphenyl)ethyl]benzoyl]indole (442 mg), ethyl 4-bromobutyrate (185 mg) and potassium carbonate (360 mg) in N,N-dimethylformamide (10 ml) was stirred at 20° C. for 4 hours. Ethyl 4-bromobutyrate (185 mg) and potassium carbonate (120 mg) were added, and resulting mixture was stirred at 20° C. for 16 hours. The reaction mixture was poured into a mixture of ethyl acetate and 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 purified by column chromatography on silica gel (20 g) eluting with a mixture of hexane and ethyl acetate (10:1) to give ethyl 4-[3-[3-[2,2-bis(4isobutylphenyl)ethyl]benzoyl]indol-1-yl]butyrate (480 mg) as an oil.
