2-(4-Aminophenylimino) derivatives of thiazolidine and -4H-5,6-dihydro-1,3-thiazines, the corresponding amide and sulfonamide derivatives, and the salts thereof are anthelmintic agents. The compounds, of which 2-(4-aminophenylimino)-N-methylthiazolidine is a typical embodiment, are prepared through cyclization of a thiourea, optionally with subsequent hydrolysis, alkylation or acetylation.n[US3860590A] |
