title: Crystal structure of isobutyl 4-(2-chloro-phen-yl)-5-cyano-6-{(E)-[(di-methyl-amino)-methyl-idene]amino}-2-methyl-4H-pyran-3-carboxyl-ate.
abstract: In the title compound, C21H24ClN3O3, the dihedral angle between the pyran ring (r.m.s. deviation = 0.037 Å) and the chloro-benzene ring is 88.56 (14)°. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating C(7) (001) chains.
