1-[2-(3,4-Dichloro­phen­yl)-5-(3,4,5-trimethoxy­phen­yl)-2,3-dihydro-1,3,4-oxadiazol-3-yl]ethanone

Abstract

The title compound, C ₁₉H ₁₈Cl ₂N ₂O ₅, was synthesized by the reaction of N′-(3,4-dichloro­benzyl­idene)-3,4,5-trimethoxy­benzo­hydrazide and acetic anhydride. The oxadiazole ring makes dihedral angles of 82.82 (7) and 9.92 (7)° with the 3,4-dichloro­benzene and the 3,4,5-trimethoxy­benzene ring planes, respectively. The crystal structure is stabilized by inter­molecular C—H⋯ O and C—H⋯ N hydrogen bonds. Intra­molecular C—H⋯O and C—H⋯N hydrogen bonds are also present.
