(Z)-N-benzyl-2,3-dihydro-2-(2-methoxybenzylidene)-4H-1,4-benzoxazine

In the title compound, C23H21NO2, the molecule contains three essentially p lanar benzo rings (A, B and C) and displays the Z-configuration. The six-me mbered oxazine ring adopts a half-boat conformation and is fused to phenyl ring A. The dihedral angle between the planar part of the oxazine moiety an d ring A is 4.70(6)degrees. A strong conjugation effect is reflected in the C-O [1.377(3)-1.385(3) Angstrom] and C-N [1.396(2) Angstrom] bond lengths.
