Azines created from substituted phenacyl aryl/cyclohexyl sulfide react with excess phosphorous oxychloride in N,N-dimethylformamide, resulting in two isomeric pyrazoles.
A potential mechanism explaining how these products form has been proposed.
The antimicrobial effectiveness of the isomeric compounds has been tested against Mycobacterium tuberculosis (MTB).
In the title compound, C(22)H(16)N(4)O(4)S, the dihedral angles between the pyrazole ring and the pendant aromatic rings are 26.2 (1), 41.1 (1) and 89.
