Synthesis of Some New Pyrazolo[3,4-d]pyrimidin-4-amines

Abstract

Some new derivatives of pyrazolo[3,4-d]pyrimidin-4-amines have been prepared through cyclocondensation reaction of 5-amino-1-phenyl-1H-pyrazole-4-carbonitriles with aryl nitriles in the presence of potassium t-butoxide in boiling t-butanol.
