A novel synthetic route to 2-amino-3-cyano-4-trifluoromethyl-6-substituted pyridines
Narsaiah, B.,Sivaprasad, A.,Venkataratnam, R. V.
, p. 87 - 90 (1994)
2-Amino-3-cyano-4-trifluoromethyl-6-substituted pyridines have been obtained from 3-cyano-4-trifluoromethyl-6-substituted-2(1H)pyridones via an interesting rearrangement of 2-O-acetamido-3-cyano-4-trifluoromethyl-6-substituted pyridine intermediates.
