✦ Synopsis

In the title compound, C~28~H~22~BrN~3~O~5~S·0.5C~4~H~10~O, the tetrahydropyrazine ring adopts a distorted half-chair conformation. The bromobenzaldehyde substituent has an axial orientation, while the 4-nitrophenyl group is in an equatorial position. The benzene rings of these substituents are not parallel, but are partially involved in intramolecular π–π stacking. In the crystal structure, the methanone molecules form a centrosymmetric dimer via intermolecular N—H...O hydrogen bonds.
