In the title compound, C20H17NO4, the double bond of the acrylonitrile group separating the 1-benzofuran moiety from the 3,4,5-trimethoxyphenyl ring has Z geometry. The 1-benzofuran groups are π–π stacked with inversion-related counterparts such that the furan ring centroid–centroid distance is 3.804 (5) Å. The dihedral angle between the planes of the trimethoxyphenyl ring and the acrylonitrile group is 24.2 (2)°.
