The title compound, C16H19NO5, which was synthesized from p-meth­oxy­cinnamic acid, has intra­molecular O—H⋯O and N—H⋯O hydrogen-bonding inter­actions. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds and aromatic π–π stacking inter­actions [minimum ring centroid–centroid separation = 3.790 (1) Å].
