  • Patent number: 4267333
    Abstract: 2-Trifluoromethyl cinchoninic acids can be prepared in high yields by reaction of an alkali metal 2-aminophenylglyoxylate and 1,1,1-trifluoroacetone in the presence of a weak acid and a metal salt of a weak acid. Preferably reaction is effected by first hydrolyzing isatin, or a substituted isatin, in the presence of an alkali metal hydroxide to produce the alkali metal 2-aminophenylglyoxylate, and then reacting this intermediate product with 1,1,1-trifluoroacetone without isolating it from the reaction medium.
