In the title compound, C11H16N2O, the dihedral angle between the mean plane of the 4-methypyridine group and the plane of the amide link is 16.7 (1)°, and there is a short intra-molecular C-H⋯O contact. Hydrogen bonding (N-H⋯O) between amide groups forms chains parallel to the b axis. Pairs of methyl-pyridine groups from mol-ecules in adjacent chains are parallel but there is minimal π-π inter-action.
在标题化合物C₁₁H₁₆N₂O中，4-甲基吡啶基团的平均平面与酰胺键平面之间的二面角为16.7 (1)°，并且存在短的分子内C-H⋯O接触。酰胺基团之间的氢键（N-H⋯O）形成平行于b轴的链。相邻链中分子的甲基吡啶基团对是平行的，但π-π相互作用最小。
