Claims
- 1. The process which comprises heating at about 80.degree. to 140.degree. C. a solution containing 3-PY-2-cyclohexen-1-one oxime, a lower-alkanoic acid and a lower-alkanoic anhydride while passing hydrogen chloride gas through the reaction mixture to produce N-(lower-alkanoyl)-3-PY-aniline and hydrolyzing said N-(lower-alkanoyl) compound under aqueous alkaline or acidic conditions at about 80.degree. to 150.degree. C. to produce the corresponding 3-PY-aniline where PY is 4- or 3-pyridinyl or 4- or 3-pyridinyl having one or two lower-alkyl substituents.
- 2. A process according to claim 1 where the oxime is heated with acetic acid, acetic anhydride and hydrogen chloride to produce N-acetyl-3-PY-aniline and hydrolyzing said N-acetyl compound to produce the 3-PY-aniline.
- 3. The process according to claim 2 where PY is 4-pyridinyl, 3-pyridinyl, 2-methyl-4-pyridinyl or 2-methyl-5-pyridinyl.
