A mixture of 3.2 g. (9.2 mmol.) of 5-chloro-3-(4-hydroxybenzoyl)-2-phenylbenzofuran, 3.5 ml. (0.035mol.) of 1,3-dibromopropane and 4.0 g. (0.029 mol.) of potassium carbonate in 100 ml. of acetone is refluxed for 3 hours. After cooling, the reaction mixture is filtered and the filtrate is concentrated to give 5-chloro-3-[4-(3-bromopropoxy)benzoyl]-2-phenylbenzofuran.
