D.-Q. Chen and S.-J. Tu

Abstract: The title compound, C₂₁H₁₅N₃O₂, was synthesized by the reaction of tetronic acid with benzaldehyde and 5-amino-3-methyl-1-phenylpyrazole in an aqueous medium under microwave irradition. Its molecular structure shows a planar fused ring system, with the N-bound phenyl ring almost coplanar with it and the C-bound phenyl ring twisted by 63.0 (1)°.
