【 摘 要 】

The title compound, C12H9N3O, is an inter­mediate in the synthesis of the muscarinic M2 receptor antagonist AFDX-384. The seven-membered ring adopts a boat conformation and the dihedral angle between the planes of the aromatic rings is 41.51 (9)°. In the crystal, mol­ecules are linked into [001] chains of alternating inversion dimers formed by pairs of N—H⋯O hydrogen bonds and pairs of N—H⋯N hydrogen bonds. In both cases, R22(8) loops are generated.
