✦ Synopsis
All the interatomic distances in the title compound, C 22 H 25 N 3 O 4 , are normal. The heteroatom ring of the quinoxalinone system shows a half-chair conformation, slightly distorted towards a sofa. In the crystal structure, the molecules dimerize via a pair of N-HÁ Á ÁO hydrogen bonds. The dimers are linked by C-HÁ Á ÁO and possible C-Hinteractions into a three-dimensional network.
