Under an argon atmosphere, 3-chloro[1,4]benzodioxino[2,3-c]pyridazine (5.0 g), sodium iodide (6.79 g) and hydrogen iodide (55%) (57.98 g) were added and the mixture was stirred at 140° C. for 1 hr. The reaction mixture was diluted with ethyl acetate and aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted. The organic layer was dried over anhydrous sodium sulfate, and the solvent was concentrated under reduced pressure to give 3-iodo[1,4]benzodioxino[2,3-c]pyridazine (1.95 g).
