Ethyl 2-{N-[N-(4-chloro-6-methoxypyrimidin-2-yl)carbamoyl]sulfamoyl}benzoate

Abstract

The asymmetric unit of the title compound, C15H15ClN4O6S, contains two independent molecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 75.21 (3) and 86.00 (3)°. Intramolecular 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, intermolecular N—H...O hydrogen bonds link the molecules.
