In the title compound, C(17)H(16)ClNO(3), the 4-hy-droxy-3-meth-oxy-benzyl group is planar [maximum atomic deviation = 0.0138 (16) Å] and is nearly perpendicular to the chloro-benzene ring, making a dihedral angle of 84.67 (4)°. The chloro-benzene and amide groups are located on the opposite sides of the C=C bond, showing an E configuration. The relatively long C=O bond distance of 1.2364 (19) Å and the short C-N bond distance of 1.341 (2) Å suggest electron delocalization in the amide fragment. Inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonding is present in the crystal structure.
在标题化合物C(17)H(16)ClNO(3)中，4-羟基-3-甲氧基苄基平面性良好[最大原子偏差 = 0.0138 (16) Å]，且几乎垂直于氯苯环，二面角为84.67 (4)°。氯苯和酰胺基团位于C=C键的两侧，呈E构型。相对较长的C=O键距为1.2364 (19) Å，较短的C-N键距为1.341 (2) Å，表明酰胺片段中存在电子离域。晶体结构中存在分子间O-H⋯O、N-H⋯O和弱C-H⋯O氢键。
