実験手順

500 mg of 4-(3-thienyl)-1-phthalazinone and 3 ml of phosphorus oxychloride were dissolved in 6 ml of dichloroethane, and the solution was stirred at 100° C. for 4 hours. The reaction solution was distilled off, and a 1-N aqueous NaOH solution was added thereto under cooling with ice. The solution was extracted with chloroform and dried over magnesium sulfide. The solvent was then distilled off, thereby obtaining 515 mg of 1-chloro-4-(3-thienyl)phthalazine.
