By interaction of 2-aryl-4-cyano-1,3-oxazole-5-sulfonylchlorides with 5-amino-3R-1Н-pyrozoles and 5-amino-1Н-1,2,4-triazole were obtained 5-[(3-R-5-Amino-1H-pyrazol-1-yl)sulfonyl]-2-aryl-1,3-oxazol-4-carbonitriles and 5-[(5-amino-1H-1,2,4-triazol-1-yl)sulfonyl]-2-aryl-1,3-oxazol-4-carbonitriles, which under action of sodium hydride eliminate sulfur dioxide and undergo cyclocondensation into new heterocyclic systems – oxazolo[5,4-d]pyrazolo[1,5-a]pyrimidine and oxazolo[5,4-d][1,2,4]triazolo[1,5-a]pyrimidine.
