Abstract
The dimethoxypbenzene ring in the title compound, C(19)H(21)NO(5), 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-H⋯O and C-H⋯O hydrogen bonds and several short-contact inter-actions (2.07-3.45 Å) create chains parallel to [110]. The phenyl ring is disordered over two orientations in a 0.54 (2):0.46 (2) ratio.
