The title compound, C 19 H 17 N 3 O 3 ÁCH 3 OH, was synthesized by the reaction of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydropyrazol-3-one and 4-formylbenzoic acid in methanol solution. As expected, the antipyrine derivative adopts a trans configuration about the central C N bond. In the crystal stru
In the title compound, C 25 H 23 N 3 O 5 S, the vanillin group makes dihedral angles of 1.42 (11), 63.76 (10) and 51.00 (10) , respectively, with the pyrazolone ring, the phenyl ring attached to the sulfonyl group, and the phenyl ring attached to the pyrazolone ring. The crystal packing is governed
