Abstract:2-Hydroxy-6-trifluoromethyl nicotinonitrile is an important intermedia |
Abstract:2-Hydroxy-6-trifluoromethyl nicotinonitrile is an important intermediate for synthesizing flupyrsulfuron-methyl-sodium, which is a broad-spectrum postemergence herbicide. 2-Hydroxy-6-trifluoromethyl nicotinonitrile was obtained starting from trifluoroacetic anhydride and vinyl ether in 59.2% total yield by acylatoin, ammonolysis and cyclization. The structure is characterized by 1H NMR. |
Key words:vinyl ether; trifluoroacetic anhydride; 2-hydroxy-6-trifluoromethyl nicotinonitrile; flupyrsulfuron-methyl-sodium |
