Abstract

Syntheses and rearrangements of 3-amino-5-aryl-4-imino-7-(p-tolyl)-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidines 3 to the 4-hydrazino-7H-pyrrolo[2,3-d]pyrimidines 4 were carried out; the 2-(unsubstituted or substituted) 9-aryl-7-(p-tolyl)-7H-pyrrolo[3,2-e][1,2,4]triazolo[1,5-c]pyrimidines 6–12 and 14, ureas 13a–c and thioureas 13d–h were obtained from 3 and the hydrazones 15 from 4.
