The title compound, CHNO, was prepared by Pictet-Spengler cyclization of tryptamine and 4-formyl coumarin. In the mol-ecule, the dihedral angle between the mean planes of the coumarin and β-carboline ring systems is 63.8 (2)°. In the crystal, mol-ecules are linked N-H⋯N hydrogen bonds, forming chains along the -axis direction. Within the chains, there are a number of offset π-π inter-actions present [shortest inter-centroid distance = 3.457 (2) Å].
标题化合物CHNO是通过色胺与4-甲酰基香豆素的Pictet-Spengler环化反应制备的。在分子中，香豆素和β-咔啉环系统平均平面之间的二面角为63.8（2）°。在晶体中，分子通过N-H⋯N氢键相连，沿轴方向形成链。在这些链中，存在许多偏移π-π相互作用[最短质心间距 = 3.457（2）Å]。
