Abstract

In the title compound, C18H15ClFN3O4, the dihedral angle between the substituted pyridine ring and the oxadiazo­line ring is 9.73 (19)° and the acyl group is coplanar with the oxadiazo­line ring [O—C—N—C torsion angle = −2.1 (3)°]. Furthermore, the substituted benzene ring is almost orthogonal with the oxadiazo­line ring, the dihedral angle between them being 87.56 (18)°.
