## Abstract magnified image The 7βarylβ4,7βdihydro[1,2,4]triazolo[1,5β__a__]pyrimidines **1a**, **1b**, **1c** can undergo addition of hydrazine to the enamine double bond leading to hydrazine derivatives of tetrahydrotriazolopyrimidines **2a**, **2b**, **2c**; the process is usually accompanied by
The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-amino-1-guanyl-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with an H atom at the triazine N atom was observed in the crystal structure. The compound crystallizes with two almost identical molecules in t
