Reaction Steps

A suspension of 200 mg (1 mmol) of Compound 12, 385 mg (1.5 mmol) of 1-(3-chloropropyl)-4-(4-fluorophenyl)piperazine and 207 mg (1.5 mmol) of potassium carbonate in 15 ml of 2-butanone was refluxed for 24 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column (eluent: chloroform), whereby 335 mg of the title compound were obtained (yield: 80%).
