Crystal structure of N-(2-amino-5-cyano-4-methyl-sulfanyl-6-oxo-1,6-dihydropyrimidin-1-yl)-4-bromo-benzene-sulfonamide di-methyl-formamide monosolvate.

The title compound, C12H10BrN5O3S2·C3H7NO, displays an almost planar amine group. The inter-planar angle between the rings is 31.72†(6)°. The residues are associated into ribbons parallel to [110] by three classical hydrogen bonds; one from each amine Hamine to ODMF and one from NHamide to Ooxo. Adjacent ribbons are connected by translation parallel to the c axis by a 'weak' hydrogen bond Hmeth-yl⋯Osulfon-yl to form a layer structure parallel to (1-10), while a further contact Hbromo-phen-yl⋯Osulfon-yl connects the residues in the third dimension.
