Abstract: The dimethoxypbenzene ring in the title compound, C19H21NO5, is gauche to the amide group and anti to the ester group. The chirality was confirmed to be S from two-dimensional NMR spectroscopy. In the crystal, N-HO and C-HO hydrogen bonds and several short-contact interactions (2.07-3.45 Å) create chains parallel to . The phenyl ring is disordered over two orientations in a 0.54 (2):0.46 (2) ratio.
