To a 200-mL three-neck flask were added 3.3 g (20 mmol) of 1-chloroisoquinoline, 4.3 g (20 mmol) of 3-bromobenzoylhydrazine, and 80 mL of para-xylene. This mixture was refluxed at 150° C. for 14 hours under a nitrogen stream. After a predetermined time elapsed, this mixture was cooled to room temperature, and the precipitated solid was collected by suction filtration. The obtained solid was washed with toluene, a saturated aqueous solution of sodium hydrogen carbonate, and water. This solid was dried, so that the substance which was the object of the synthesis was obtained as 6.2 g of a pale yellow powder in 90% yield.
