✦ Synopsis

The piperidine and cyclohexane rings in the title compound, C 19 H 25 NO 3 , are trans-fused and adopt boat and chair conformations, respectively. The phenyl and ester substituents are oriented axially with respect to the decahydroquinoline moiety. The N atom of the piperidine ring exists in a planar configuration. The keto O atom of the ester group exhibits positional disorder, with an 80:20 population ratio. The crystal structure is stabilized by C-HÁ Á ÁO hydrogen bonds.

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
