Cesium carbonate → 3-{5-(3-Methoxycarbonylbenzoyl)-3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-2-thienyl}-propionic acid methyl ester

Participants

Reaction Steps

804 mg of cesium carbonate is added to a solution of 430 mg of 3-[5-(3-Methoxycarbonylbenzoyl)-3-hydroxy-2-thienyl]-propionic acid methyl ester and 332 mg of (1E)-6-bromo-1-(4-methoxyphenyl)-1-hexene in 2.9 ml of dimethylformamide and the suspension is stirred for 21 hours at room temperature. The reaction mixture is filtered, the filtrate residue is washed with dichloromethane, the filtrate is concentrated by evaporation and the residue is chromatographed on silica gel with hexane. 542 mg of the title compound is obtained as colorless oil.
