dc.description.abstractA series of 4-arylamino-8-(alkyl or aryl)hydrazidepyrimido[5,4-d]pyrimidines was obtained efficiently from 6-carbohydrazonamidepurines by reaction with piperidine. The 6-carbo-hydrazonamidepurines were generated selectively by the reaction of 6-imidatopurine with hydrazides under acidic conditions.por
