Abstract

In the title compound, C(21)H(15)NO(3), the dihedral angle formed between the aromatic ring systems is 71.50 (3)°. The meth-oxy group is coplanar with the benzene ring to which it is connected, the C-O-C-C torsion angle being 6.37 (17)°. The observed conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring.
