Abstract: In the title molecule, C5H6BrN3, the pyrimidine ring is essentially planar, with an r.m.s. deviation of 0.007 Å. The Br and N atoms substituted to the pyrimidine ring are coplanar with the ring [displacements = 0.032 (1) and 0.009 (5) Å, respectively], while the methyl C atom lies 0.100 (15) Å from this plane with a dihedral angle between the pyrimidine ring and the methylamine group of 4.5 (3)°. In the crystal, C-HN, C-HBr and N-HN hydrogen bonds link the molecules into a two-dimensional network in the (011) plane.
