1-(4-Methoxy-phenyl-sulfon-yl)-5-methyl-5-phenyl-imidazolidine-2,4-dione.

The title compound, C(17)H(16)N(2)O(5)S, crystallized in the chiral monoclinic space group P2(1), with two enanti-omeric mol-ecules (A and B) in the asymmetric unit. It is composed of a methyl-imidazolidine-2,4-dione unit substituted with a phenyl group and a 4-methoxy-phenyl-sulfonyl group. The benzene ring mean planes are inclined to one another by 22.20 (14)° in mol-ecule A and by 15.82 (13)° in mol-ecule B. In the crystal structure, the A and B mol-ecules are linked by N-H⋯O hydrogen bonds, forming centrosymmetric dimers. A number of C-H⋯O inter-actions are also present in the crystal structure, leading to the formation of a three-dimensinoal network.
