The title compound, C(12)H(14)BrN(3)O, is built up from two fused six-membered rings and one six-membered ring linked through a spiro C atom. The hydro-pyrimidine ring has an envelope conformation and the cyclo-hexane ring is in a chair conformation. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming a mol-ecular tape along the b axis.
