The title structure, C(9)H(11)N(3)O(2), is a racemate. The chiral centre is situated at the N-C-N C atom of the imidazolidine ring. The inter-planar angle between the mean planes of the pyridine and imidazolidine rings is 89.41 (5)°. The methyl group is in a trans position with respect to the pyridine N atom. In the crystal, the mol-ecules are arranged in zigzag layers parallel to the b axis. The mol-ecules within the layers are inter-connected by strong O-H⋯N and weak N-H⋯O hydrogen bonds; the former take place between OH groups and amine N atoms and the latter between the amine N atom and the carbonyl O atom. In addition, C-H⋯O inter-actions are also present.
标题结构C(9)H(11)N(3)O(2)为外消旋体。手性中心位于咪唑烷环的N-C-N C原子上。吡啶环和咪唑烷环平均平面之间的面间角为89.41 (5)°。甲基相对于吡啶N原子处于反式位置。在晶体中，分子沿b轴平行排列成锯齿状层。层内分子通过强O-H⋯N和弱N-H⋯O氢键相互连接；前者发生在OH基团和胺N原子之间，后者发生在胺N原子和羰基O原子之间。此外，还存在C-H⋯O相互作用。
