実験手順

24.6 g (140 mmol) of 4-hydroxy-3-methyl-2H-isoquinolin-1-one are heated together with 9.13 g (294 mmol) of red phosphorus in 55% hydriodic acid (130 ml) at 160° C. for 7 days. The cooled mixture is poured into water and extracted with dichloromethane. 10.2 g (46% yield) of a white solid are obtained.
