The title compound, C 14 H 18 N 2 O 2 S, which was obtained from an extended Biginelli reaction, contains a pyran ring with a chair conformation, a pyrimidine ring with a half-chair conformation and a benzene ring. The crystal structure is stabilized by an intermolecular hydrogen-bond network.
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.
