چکیده
There are two mol-ecules in the asymmetric unit of the title compound, C(8)H(4)ClNO(2). In the crystal, they are linked by N-H⋯O hydrogen bonds, generating centrosymmetric, tetra-meric assemblies. A C-H⋯O inter-action also occurs.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(10)ClNO(2), which differ in the dihedral angles between the mean planes of the phenyl ring and the 4-chloro-indoline-2,3-dione ring system [59.48 (9) and 79.0 (1)°]. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds, forming polymeric chains in [100].

Treatment of 5,6-dimethoxy-2-(methylphenylcarbamoyl)-benzofuran-3carboxylic acid with PPA yielded 2,3-dimethoxy-7-methyl-7,12-dihydro-6H-[1]benzofuro-[2,3-c]-[1]-benzazepin-6,12-dione. The analogous 2-[(5,6-dimethoxybenzofuran-2-carbonyl)methylamino]benzoic acid was resistant to cyclization, whereas 2-[(6methoxybenzofuran-2-carbonyl)-amino]benzoic acid underwent cyclization to the corresponding...
