title: (Z)-Isobutyl 2-benzamido-3-(4-chloro-phen-yl)acrylate.
abstract: The title compound, C(20)H(20)ClNO(3), is a α-amino acid derivative which displays a Z configuration about the C=C double bond. The dihedral angle betwen the aromatic rings is 87.75 (12)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond. In the crystal structure, centrosymmetrically related mol-ecules inter-act through inter-molecular C-H⋯O hydrogen-bond inter-actions, forming dimers. The dimers are further linked into chains parallel to the a axis by N-H⋯O hydrogen bonds. The methyl groups of the isopropyl group are disordered over two positions with occupancy factors of 0.5.
