Abstract

3-Arylamino-4-cyano-5-phenylpyrazoles and 3-aryl-4-phenyl-2-[(benzoyl)cyanomethyl-ene]-4, 5-thiazolines, respectively, were obtained by condensation of benzoylcyanothioacetic acid arylamides with hydrazine hydrate or withΩ-bromoacetophenone. 2-[(Benzoyl)-cyanomethyl] benzothiazole derivatives were synthesized by oxidative cyclization of benzoylcyanothioacetic acid arylamides.
