反応手順

To a solution of 8-methylquinoline 1-oxide (0.440 g, 2.764 mmol) in toluene (10 ml) was added phosphoryl trichloride (1.265 ml, 13.82 mmol), and the reaction was heated to 80° C. for 2 hours. The reaction was cooled to ambient temperature and concentrated. The crude material was taken up in EtOAc and washed with saturated sodium bicarbonate and saturated sodium chloride. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated to yield the desired compound (0.4 g, 2.252 mmol, 81.47% yield).
