A mixture of ethyl 4-[1-(4-hydroxybenzoyl)indolizin-3-yl]butyrate (61 mg), 1-bromo-1-(4-isobutylphenyl)propane (53 mg) and potassium carbonate (72 mg) in N,N-dimethylformamide (2 ml) was stirred at room temperature for 18 hours. The reaction mixture was filtered and the filtrate was poured into a mixture of ethyl acetate and 0.5N hydrochloric acid. The organic layer was separated, washed with water and brine, dried over magnesium sulfate and evaporated. The residue was chromatographed on silica gel eluting with n-hexane and ethyl acetate (2:1) to give ethyl 4-[1-[4-[1-(4-isobutylphenyl)propyloxy]benzoyl]indolizin-3-yl]butyrate (80 mg) as an oil.
