Catalytic action of azolium salts. IX. Synthesis of 6-aroyl-9H-purines and their analogues by nucleophilic aroylation catalyzed by imidazolium or benzimidazolium salt

In the presence of 1,3-dimethylimidazolium iodide (1), 6-chloro-9- phenyl-9H-purine (7) and 4-chloro-5,6-dimethylpyrrolo[2,3-d]pyrimidines 40- 42 underwent nucleophilic aroylation with arenecarbaldehydes (5) to give the corresponding fused aroylpyrimidine
