摘要：

In the title compound, C13H15NO2, the hexahydropyrrolo[2,1-c][1,4]oxazine fragment is disordered over two conformations (A and B) in a 0.656 (5):0.344 (5) ratio. The five-membered ring is similarly disordered and adopts an envelope conformation in A, while in B this ring is nearly planar [maximum deviation = 0.088 (1) angstrom]. The six-membered rings in both A and B exhibit chair conformations. In the crystal, weak intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into ribbons propagating in [010].
