Crystal structure of 2-(4-acetyl-anilino)-2-oxoethyl 3-(4-hy-droxy-phen-yl)propionate.

ABSTRACT: In the title compound, C19H19NO5, the amide carbonyl O atom is positioned anti to the other two carbonyl O atoms. The 4-hy-droxy-hydro-cinnamate fragment is disordered over two positions with an occupancy ratio of 0.729 (12):0.271 (12). The N-(C=O)-C plane of the acetamide group and the acetate O-(C=O)-C plane are almost co-planar; the acetamide plane makes dihedral angles of 1.9 (6) and 16.0 (19)°, respectively, with the acetate planes of the major and minor occupancy components. In the crystal, N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular sheet structure parallel to (102).
