title: (Z)-7-Chloro-3-[(3-chlorophenyl)-methylidene]-4-p-tosyl-3,4-dihydro-2H-1,4-benzoxazine.
abstract: In the title compound, C22H17Cl2NO3S, the molecule is a substituted 3,4-dihydro-2H-1,4-benzoxazine compound which has three phenyl rings which are essentially planar. The 3,4-dihydro-2H-oxazine part of the molecule is fused to the benzo ring and has a half-boat conformation; the dihedral angle between the planar part of the oxazine ring and the benzo ring is 10.2 (2) degrees. The (3-chlorophenyl)methylidene substituent has a Z configuration in relation to the ring N atom of the oxazine moiety. Interestingly, the p-toluenesulfonyl (p-tosyl) substituent on the ring N atom protrudes away from the 3-chlorophenyl substituent thus avoiding any steric interaction.
