N-(6-Bromo-4-oxo-3,4-di­hydro­pteridin-2-yl)-2,2-di­methyl­propan­amide

In the title compound, C₁₁H₁₂BrN₅O₂, the rings in the pterin moiety are planar. The carbonyl O atom is in a synperiplanar conformation, while the C—N—C(=O)—C linkage is antiperiplanar. N—H⋯N and N—H⋯O intermolecular hydrogen bonds transform the mol­ecules into infinite chains.
