In the title molecule, C20H18N2O3, the pyrazole ring forms a dihedral angle of 2.2 (1)° with its methoxyphenyl substituent and a dihedral angle of 67.2 (1)° with the benzene substituent on the propenal unit. In the crystal, molecules are connected by weak C—HO hydrogen bonds, forming R22(26) and R22(28) cyclic dimers that lie about crystallographic inversion centres. These dimers are further linked through C—HO and C—HN hydrogen bonds, forming C(8), C(9), C(10) and C(16) chain motifs. These primary motifs are further linked to form secondary C22(15) chains and R22(18) rings.

In the title compound, C30H28Cl3NO5S, the pyrrolidine ring adopts an envelope conformation (with the N atom as the flap) and the thiazine ring is in a distorted chair conformation. The molecular structure shows three intramolecular C—HO interactions leading to self-associated ring S(6) and two S(7) motifs. In the crystal, the molecules are linked by C—HO and C—HCl interactions. Two R22(10) and one R22(16) centrosymmetrically related ring motifs are observed in the unit cell and they are connected through C(6) and C(11) chain motifs extending along the b and c axes, respectively.
