반응 단계
A mixture of 2.0 g. (6.4 mmol.) of 3-(4-hydroxybenzoyl)-2-phenylbenzofuran, 1.3 g. (6.4 mmol.) of 3-di-n-butylaminopropyl chloride and 4.0 g. (0.04 mol.) of anhydrous potassium carbonate in 20 ml. of dry 2-butanone is refluxed for 18 hours. The reaction is cooled, water and ether are added and the layers are separated. The organic phase is extracted with 10% aqueous sodium hydroxide and the aqueous layers are combined and extracted again with water. The combined ether extracts are concentrated under reduced pressure to give the title compound.
