In the title compound, C~9~H~13~N~8~O~2~ ^+^Β·C~7~H~3~N~2~O~6~ ^β^, the aminopyrimidine molecule is protonated at one of the pyrimidine N atoms. The carboxylate group of the 3,5-dinitrobenzoate anion interacts with the protonated N atom and the 2-amino group in a nearly linear fashion through a pair
The title compound, C~20~H~17~NO~6~, was synthesized by the reaction of syringaldehyde with hippuric acid. The molecule adopts a __Z__ configuration about the central olefinic bond. The two benzene rings and the oxazolone ring are almost coplanar. The crystal structure is stabilized by weak intermol
