    公开(公告)日:1977-05-31
    3-(4 OR 3-Pyridinyl)-2-cyclohexen-1-ones (I) and their oxime derivatives are useful in preparing (3-aminophenyl)-pyridines, in turn, useful in preparing known antibacterial agents. Also shown is the preparation of I by starting with the reaction of methyl vinyl ketone with either 1-(pyridinyl)-1-(lower-tertiary-amino)-ethylene (II) or lower-alkyl 3-(pyridinyl)-3-oxopropanoate. Also shown is the process of converting I to its oxime, acylating the oxime and heating the acylated oxime under acidic conditions to produce N-(lower-acyl)-3-(pyridinyl)-aniline (VII), and hydrolyzing VII under aqueous alkaline conditions to produce the corresponding 3-(pyridinyl)aniline.

    An improved method of preparing 3-(4-pyridinyl)-2-cyclohexen-1-one oxime from ethyl 5-oxo-2-[(4-pyridinyl)-carbonyl]hexanoate is a one pot sequence which comprises first heating ethyl 5-oxo-2-[(4-pyridinyl)carbonyl]hexanoate with excess sulfuric acid, neutralizing the excess acid, extracting the resulting 3-(4-pyridinyl)-2-cyclohexen-1-one with isopropyl alcohol, draining off the heavier aqueous layer, adding hydroxylamine hydrochloride to the isopropyl alcohol solution of said 2-cyclohexen-1-one, stirring the mixture at reflux, basifying the mixture and evaporating it to dryness, and isolating 3-(4-pyridinyl)-2-cyclohexen-1-one oxime from the residue. The oxime is an intermediate for preparing 3-(4-pyridinyl)aniline, in turn, an intermediate for preparing rosoxacin, an antibacterial agent.
