Abstract: The title compound, C₁₂H₁₄BrN₃O, is built up from two fused six-membered rings and one six-membered ring linked through a spiro C atom. The hydropyrimidine ring has an envelope conformation and the cyclohexane ring is in a chair conformation. In the crystal, molecules are linked by N-HO and N-HN hydrogen bonds, forming a molecular tape along the b axis.
