Abstract

In the title compound, C(23)H(23)NO(4), the dihedral angle beween the chromen-2-one ring system and the benzene ring is 69.73 (10)° and the mol-ecule adopts an E conformation with respect to the C=N double bond. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds occur, generating R(2) (2)(12) loops.
