Ethyl 2-amino-4-(3-chloro­phen­yl)-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carboxyl­ate

The title mol­ecule, C(22)H(16)ClNO(5), was obtained by the reaction of (E)-ethyl 3-(3-chloro­phen­yl)-2-cyano­acrylate and 2-hydroxy­naphthalene-1,4-dione catalysed by triethylamine in ethanol. In the crystal structure, the chlorobenzene ring makes a dihedral angle of 88.63 (4)° with the fused ring...

description The title mol­ecule, C(22)H(16)ClNO(5), was obtained by the reaction of (E)-ethyl 3-(3-chloro­phen­yl)-2-cyano­acrylate and 2-hydroxy­naphthalene-1,4-dione catalysed by triethylamine in ethanol. In the crystal structure, the chlorobenzene ring makes a dihedral angle of 88.63 (4)° with the fused ring system. The six-membered ring formed by an intra­molecular N—H⋯O hydrogen bond is almost planar. The crystal packing is stabilized by N—H⋯O hydrogen bonds.
