| Abstract: | Reaction of 2,6-dichloro-4-trifluoromethylamine with a suspension of nitrosyl sulphuric acid, followed by the reaction with a solution of ethyl 2,3-dicyanopropionate in acetic acid, gave 5-amino-3-cyano-l-(2,6-dichloro-4-trifluoromethylphenyl)pyrazole (1), which was then reacted with acetic anhydride to give 2a, reacted with maleic anhydride to give 2b, and reacted with benzoyl chloride to give 2c. All compounds were characterized by elemental analysis, IR, 1H NMR, 13C NMR and MS spectra. |
