Studies on Pyrazolopyrimidine Derivatives. XVI. Preparation of Reissert Compounds from Condensed Pyrimidine Systems Catalyzed by Lewis Acids

Among various Lewis acids, aluminium chloride (AlCl3) was the most effective catalyst for the formation of the Reissert compound (21a,5-benzoyl-4,5-dihydro-1-phenyl-1H-pyrazolo-pyrimidine-4-carbonitrile) of 1-phenyl-1H-pyrazolopyr
