The crystal structure of the title compound, C12H11N3O4, has been determine
d as part of a study of the luminescent activity of oxazolin-5-ones [Singh
& Singh (1994). Indian J. Chem. 33B, 232-235], The dihedral angle between t
he 2-oxazoline (4,5-dihydrooxazole) and phenyl rings is 12.48(8)degrees. A
conjugation effect is observed in the dimethylaminomethylene moiety.
