Abstract

In the title compound, C23H20N2O3·CH3OH, the hexa­hydro-1H-benzo[f]isoindole and indoline rings are planar, with maximum deviations of 0.092 (1) and −0.095 (1) Å, respectively. The dihedral angle between these two rings is 88.03 (4)°. An O—H⋯N inter­action links the main mol­ecule and the methanol solvent mol­ecule. An intra­molecular C—H⋯O inter­action forms an S(6) ring motif. In the crystal, the mol­ecules form two-dimensional layers parallel to the bc plane through N—H⋯O and C—H⋯O inter­actions.
