実験手順

A solution of 7-chloro-2-methylimidazo[2,1-a]isoquinoline (4 g) in N,N-dimethylformamide (40 ml) was added dropwise to a mixture of N,N-dimethylformamide (5.7 ml) and phosphoryl chloride (1.86 ml) under ice cooling. After being stirred at 85°-90° C. for 6 hours, the mixture was poured into ice-water, basified with aqueous sodium hydroxide, heated at 80° C. for 20 minutes and cooled. The resulting precipitate was collected by filtration, washed with water and recrystallized from methanol to give 7-chloro-3-formyl-2methylimidazo[2,1-a]isoquinoline (0.356 g).
