The asymmetric unit of the title compound, C(15)H(15)NO, contains two independent mol-ecules, which differ in the dihedral angle between the aromatic rings [48.98 (9) and 57.48 (8)°]. The methyl groups in para positions are disordered over two equally occupied positions. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds which link the mol-ecules into chains running along the b axis.
标题化合物C(15)H(15)NO的不对称单元包含两个独立分子，它们在芳环之间的二面角上有所不同[48.98 (9)和57.48 (8)°]。对位的甲基在两个同等占据的位置上无序排列。分子内存在N-H⋯O氢键。晶体结构通过分子间N-H⋯O氢键得以稳定，这些氢键将分子连接成沿b轴延伸的链。
