A simple and efficient new synthetic method to obtain 3-substituted quinazolin-2,4-diones 9.16 by the reaction of 3-substituted 2- thioxo-quinazolin-4-ones 1.8 with sodamide under mild conditions was presented. The structure of the newly synthesized compounds was determined by infrared spectroscopy, UV-visible spectroscopy, nuclear magnetic resonance, and single-crystal X-ray crystallographic analysis. The crystal structure of 6-methyl-3-phenylquinazoline-2,4(1H,3H)-dione (11) [C15H12N2O2: MF. 252.27, triclinic, P-1, a = 7.8495 (13) ?, b= 12.456 (2) ?, c = 13.350 (2) ?, α = 103.322 (3)°, β = 90.002 (3)°, γ = 102.671 (4)°, V. 1237.5 (3) ?3, Z= 4, R = 0.0592, wR= 0.1699, S= 1.039] was determined. In the crystal cell, two identical conformers of compound 11 were found connected by intramolecular hydrogen bonds, responsible for the favourable occurrence of these two independent molecules.

Venezuelan equine encephalitis virus (VEEV) is an emerging pathogenic alphavirus that can cause significant disease in humans. Given the absence of therapeutic options available and the significance of VEEV as a weaponized agent, an optimization effort wa
