Reaction Steps

4'-Hydroxy-8-ethoxycarbonylflavone (1 eq.) and 2-chloromethylquinoline (1.1 eq.) were dissolved in DMF, followed by the addition of potassium carbonate (1.2 eq.). The resulting mixture was stirred at 100° C. and, subsequent to the completion of the reaction, was charged into water. The water layer was extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was recrystallized from DMF-ethanol, whereby the title compound represented by the following formula was obtained (yield: 64%). ##STR21##
