چکیده
In the title compound, C18H14N2O2, the six-membered oxazine ring adopts a half-chair conformation and its mean plane makes a dihedral angle of 83.23 (7)° with the pyrrolidine ring of the indoline ring system. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains along [100]. The chains are linked by C-H⋯π inter-actions, forming slabs parallel to (001).
