Abstract: The racemic title compound, C11H12N2O3, contains a [4.3.0]bicyclic unit in which the shared C-C bond adopts a cis configuration. The five- and six-membered rings are in twisted envelope (with the bridgehead C atom bearing the methoxy substituent as the flap) and distorted chair conformations, respectively. In the crystal, the molecules are linked via weak C-H...O iteractions, forming ladder-like chains along [010].
