Procedure
7-Methoxy-3-phenylisoquinoline-2-oxide (0.30 g) was reacted with phosphorus oxychloride (3 ml) at 110° C. for 2 hr. The reaction solution was evaporated, and to the resulting residue were added ethyl acetate and an aqueous solution of saturated sodium bicarbonate. The resulting organic layer was washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane system), to give 0.20 g of the title compound was obtained as a white solid.
