The title compound, C19H17Cl3N2O3, has been prepared in a cyclo­condensation reaction between 2,3,5-tri­chloro­benzaldehye and 4-acetyl-2-methyl-1H-imidazole. The cyclo­hexenone ring adopts an envelope conformation with the C atom substituted by the tri­chloro­phenyl ring as the flap. The mutually trans ester and aryl substituents both occupy equatorial sites. In the crystal, a combination of N—H⋯O and C—H⋯N hydrogen bonds links the mol­ecules into ribbons of edge-fused centrosymmetric rings, which enclose R22(14) and R44(16) alternate ring motifs, propagating along the b-axis direction.
