実験手順

6-Methoxy-isoquinoline-N-oxide hydrochloride (1a, 85 g; 400 mmol) was carefully added in portions to phosphoryl chloride (550 mL) at a temperature of 90° C., after which the mixture was stirred for 6 h at 90° C. Excess of phosphoryl chloride was removed in vacuo. The remaining white solid was washed with water, filtered and dried in vacua. Yield: 68 g (88%); white solid; m.p. 72-74° C.; El-MS: 193 (M+).
