Crystal and molecular structures of the title compounds l b and l c have been determined by the X-ray method. Crystals of l b are monoclinic, space group P2,/c, and crystals of Ic are orthorhombic, space group P2,2,2,. The sulfinyl oxygen atom and the alkoxycarbonyl group in both compounds are trans
The NH unit on the exocyclic C C double bond in the title compound, C 30 H 23 N 3 O, lies on the same side of the double bond as the carbonyl unit of the pyrazolonyl ring, and the two interact through an NÐHÁ Á ÁO hydrogen bond [2.671 (2) A Ê ].
