biostudies-literatureUnknown71(Pt 5)Boukharsa YIn the title compound, C18H17ClN2O4, the dihedral angle between the benzofuran ring system [maximum deviation 0.014 (2) Å] and the oxopyradizine ring is 73.33 (8)°. The structure is characterized by disorder of the ethyl group, which is split into two parts, with a major component of 0.57 (3), and the acetate carbonyl O atom, which is statistically disordered. In the crystal, the molecules are linked by C-H⋯O inter-actions, forming a three-dimensional network.Acta crystallographica.
