反应详情

A solution of 2-chloro-4-phenylquinoline (2.0 g) and 1-ethylpiperazine (2.7 g) in toluene (15 ml) is heated under reflux for 10 hours. To the reaction mixture is added water and the resulting mixture is extracted with ethyl acetate. The extracts are dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue is chromatographed on silica gel (25 g) using chloroform as an eluent. Fractions containing the title compound are pooled and concentrated to give the title compound (2.3 g).
