Abstract :
Substituents of fully new pyrazolo[3,4-d]pyrimidines were synthesized. The synthesis starts with cyanomethylphenylketone that reacts with phenyl hydrazine to produce the corresponding aminopyrazole. The latter undergoes a cyclocondensation with N,N0-bis(arylmethylidene)arylmethane, yielding the final product. Both synthetic steps are high yielding (the overall yields between 65-78%). The newly synthesized compounds were characterized by 1H NMR, 13C NMR, and elemental analysis.
