    摘要: The present invention provides a process for producing carbostyril derivatives (I) which are known to be useful as medical drug such as antithrombotic agent, cerebral circulation improver, anti-inflammatory agent, antiulcer agent, etc. in a high yield and a high purity. The carbostyril derivatives (I) can be produced by reacting a carbostyril derivative (II) with a tetrazole derivative (III) in the presence of a phase transfer catalyst.

    摘要: The present invention provides an industrially advantageous method of producing aminophenol compounds represented by the formula (1) by a simple and easy procedure at a high yield and a high purity. The present invention provides a method of producing an aminophenol compound represented by the formula (1): (wherein each of R1 and R2, which may be the same or different, is a hydrogen atom, a substituted or unsubstituted lower alkyl group or the like; R1 and R2, taken together with the adjacent nitrogen atom, may form a 5- or 6-membered heterocycle with or without other intervening heteroatoms; the heterocycle may be substituted by 1 to 3 substituents selected from the group consisting of a hydroxyl group, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aryloxy group and the like; and the hydroxyl group in the formula (1) is substituted on the 2- or 4-position to the amino group on the phenyl ring), which comprises allowing a cyclohexanedione compound represented by the formula (2) to react with an amine compound represented by the formula (3) (wherein R1 and R2 are as defined above), under a neutral or basic condition.

    摘要: An object of the present invention is to provide a method for producing an oxazole compound in a high yield. The object can be achieved by a compound represented by Formula (11): wherein R
    1 is a hydrogen atom or lower-alkyl group; R
    2 is a 1-piperidyl group substituted at the 4-position with a substituent selected from (A1a) a phenoxy group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups, (A1b) a phenoxy-substituted lower-alkyl group substituted on the phenyl moiety with one or more halogen-substituted lower-alkyl groups, (A1c) a phenyl-substituted lower-alkoxy lower-alkyl group substituted on the phenyl moiety with halogen, (A1d) a phenyl-substituted lower-alkyl group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups, (A1e) an amino group substituted with a phenyl group substituted with one or more halogen-substituted lower-alkoxy groups, and a lower-alkyl group, and (A1f) a phenyl-substituted lower-alkoxy group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups; n is an integer from 1 to 6; and X
    3 is an organic sulfonyloxy group.
