چکیده

The mol-ecule of the title compound, C(27)H(24)N(4)O(5), exists in the keto-enamine tautomeric form, stabilized by an intra-molecular N-H⋯O hydrogen bond. An intra-molecular C-H⋯·O hydrogen bond also occurs. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into chains.

In the title compound, C(25)H(23)N(3)O(3)S, an intra-molecular N-H⋯O inter-action generates an S(6) ring, which stabilizes the enamine-keto form of the compound. This S(6) ring and the pyrazole ring are essentially coplanar, making a dihedral angle of 1.49 (6)°. The bond lengths within the S(6) ring of the mol-ecule lie between classical single- and double-bond lengths, indicating extensive con...
