title: Ethyl 2-{N-[N-(4-chloro-6-methoxy-pyrimidin-2-yl)carbamo-yl]sulfamo-yl}benzoate.
abstract: The asymmetric unit of the title compound, C(15)H(15)ClN(4)O(6)S, contains two independent mol-ecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 75.21 (3) and 86.00 (3)°. Intra-molecular N-H⋯N and C-H⋯O hydrogen bonds result in the formation of two five- and two six-membered rings. The six-membered rings have flattened-boat conformations, while the five-membered rings adopt envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.
