摘要
The title compound, C15H17NO4, containing two molecules in the asymmetric unit is a polymorph of the crystal structure published by Martinez et al. [(2011). Eur. J. Org. Chem. pp. 3137-3145] which at 120 K is monoclinic with one molecule in the asymmetric unit. Both molecules in the title compound are in the trans form. In the crystal, N-HO and O-HO hydrogen bonds connect molecules, forming a two-dimensional network parallel to (001).
