  • Processes for producing 2-chloro-3-trifluoromethylpyridine
    Patent number: 8691997
    Abstract: The present invention provides processes for producing 2-chloro-3-trifluoromethylpyridine which is useful as an intermediate for medicines and agrochemicals, at a high production rate in a high yield. Specifically, the present invention relates to a process for producing 2-chloro-3-trifluoromethylpyridine or a salt thereof comprising allowing 3-trifluoromethylpyridine N-oxide to react with a chlorinating agent; and also relates to a process for producing 2-chloro-3-trifluoromethylpyridine or a salt thereof comprising oxidizing 3-trifluoromethylpyridine to produce 3-trifluoromethylpyridine N-oxide and subsequently allowing the obtained 3-trifluoromethylpyridine N-oxide to react with a chlorinating agent.

  • Processes for producing 1-substituted-2-cyanoimidazole compounds
    Patent number: 5869683
    Abstract: A process for producing 1-substituted-2-cyanoimidazole compounds is described, which comprises (1) undergoing a reaction of a compound represented by formula (IV), hydroxylamine or a mineral acid salt thereof, and glyoxal or glyoxime to produce a compound represented by formula (III), (2) undergoing a reaction of the compound represented by formula (III) with thionyl chloride or thionyl bromide in the presence of N,N-dialkylamide to produce a reaction mixture, and then reacting the produced reaction mixture with sulfur chloride to produce a 2-cyanoimidazole compound represented by formula (II), and (3) undergoing a sulfamoylation reaction and an isomerization reaction of the 2-cyanoimidazole compound represented by formula (II) and a compound represented by formula (V) in the presence of at least one base selected from carbonates of alkali metals and bicarbonates of alkali metals and a polar solvent to produce a 1-substituted-2-cyanoimidazole compound represented by formula (I-b).
