There are two independent molecules in the asymmetric unit of the title compound, C16H17NO4, with similar conformations but some differences in their bond angles. Each molecule adopts a trans configuration with respect to the methylidene C N bond and is twisted with a dihedral angle between the two substituted benzene rings of 80.52 (7)� in one molecule and 83.53 (7)� in the other. All methoxy groups are approximately coplanar with the attached benzene rings, with Cmethyl—O—C—C torsion angles ranging from �6.7 (2) to 5.07 (19)�. In the crystal, independent molecules are linked together by O—H� � �N and O—H� � �O hydrogen bonds and a �–� interaction [centroid–centroid distance of 3.6030 (9) A ° ], forming a dimer. The dimers are further linked by weak C— H� � �O interactions and another �–� interaction [centroid– centroid distance of 3.9452 (9) A ° ] into layers lying parallel to the ab plane.
