Abstract
In the title compound, C17H17NO2, the phenylene rings are bent with respect to the carbon–carbon double bond [dihedral angle between rings = 39.6 (1)°]. The acetamido group is twisted out of the plane of the aromatic ring [dihedral angle = 44.2 (1)°] in order to form an N–H⋯O hydrogen bond to the acetamido group of an adjacent molecule, generating a zigzag chain running along the c axis.

Experimental
The compound was synthesized in a study on indolostilbenes (Ahmad et al., 2009). Crystals were grown from its solution in ethyl acetate.
Refinement
Hydrogen atoms were placed at calculated positions (C–H 0.95–0.98 Å) and were treated as riding on their parent carbon atoms, with U(H) set to 1.2–1.5 times U~eq~(C). The amino H-atom was located in a difference Fourier map, and was refined with a distance restraint of N–H 0.88±0.01 Å; its temperature factor was refined.
