In the title mol-ecule, C(29)H(32)N(2)O(3), the piperazine ring has a chair conformation. The amide N atom is almost planar (bond angle sum = 359.5°), whereas the other N atom is clearly pyramidal (bond angle sum = 330.4°). The dihedral angle between the meth-oxy-benzene rings is 81.29 (16)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds.
在标题分子C(29)H(32)N(2)O(3)中,哌嗪环呈椅式构象。酰胺N原子几乎呈平面状(键角总和 = 359.5°),而另一个N原子明显呈金字塔形(键角总和 = 330.4°)。甲氧基苯环之间的二面角为81.29 (16)°。在晶体中,分子通过C—H⋯O氢键相连。
