چکیده
In the title compound, C(18)H(21)NO(3), the C=N bond has a trans conformation and the benzene rings are oriented at a dihedral angle of 61.32 (6)°. The C atoms of the three meth-oxy groups are all roughly coplanar with their attached ring [deviations = 0.219 (2), -0.097 (2) and -0.137 (2) Å]. In the crystal, a weak C-H⋯π inter-action may help to establish the packing.
