In the title 3-cyano-pyridine derivative, C21H19N3O4, the 3-cyano-substituted pyridine ring forms dihedral angles of 2.35 (5) and 41.60 (5)° with the unsubstituted pyridine and 2,4,5-trimeth-oxy-substituted benzene rings, respectively. The dihedral angle between the unsubstituted pyridine and benzene rings is 39.84 (5)°. The meth-oxy groups form Cmeth-yl-O-C-(C,N) torsion angles in the range 0.80 (15)-11.45 (15)°. In the crystal, mol-ecules related by 21 screw axes are linked by weak C-H⋯N hydro ...[more]
