The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-guanidino-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with the NH H atom vicinal to the methyl groups was observed in the crystal structure. The triazine ring adopts a flattened half-boat conformation.
In the structure of the title compound, C 21 H 17 FN 4 O 2 S 2 , the fused thiazolopyrimidine ring system is nearly planar. The morpholine ring adopts a chair conformation. The crystal structure is stabilized by C-HÁ Á ÁO hydrogen bonds and weak stacking interactions.
