【 摘 要 】

The asymmetric unit of the title solvate, C21H22N2O2·CH3OH, contains one methanol solvent mol­ecule and one mol­ecule of the heterocycle that is built up by the fusion of four six-membered rings A, C, D, E and one five-membered ring B. The indole moiety (rings A and B) is essentially planar, with an r.m.s. deviation of 0.013 Å, whereas rings C and D adopt a twisted conformation with a trans-ring junction. In the crystal, two heterocyclic mol­ecules are associated with two methanol mol­ecules through mutual N—H⋯O and O—H⋯N hydrogen bonds, forming a centrosymmetric dimer.
