    • A process for producing a carboxylic acid derivative represented by general formula [VIII], (wherein R , R , R and L are each as defined in the specification), which comprises reacting a benzyl halide with a cyano compound to give a phenylacetonitrile, reacting the nitrile with an alkyl nitrite in the presence of a base to give an alpha -hydroxyiminophenylacetonitrile, reacting the hydroxy nitrile with an alkylating agent to give an alpha -alkoxyiminophenylacetonitrile, hydrolyzing the alkoxy nitrile in the presence of a base, optionally after hydration and acid treatment, to give an alpha -alkoxyiminophenylacetic acid, and finally reacting the acid with a halogenating agent, or converting the acid into a corresponding metal salt and reacting the salt with an alkylating agent, or reacting the acid with a lower alcohol in the presence of an acidic catalyst. According to this process, the reactions can be advanced through the respective steps under mild conditions, and the target derivative [VIII] can be produced even without resort to high-pressure steam equipment, high-temperature heat medium equipment, refrigerator, and so forth. Further, this process is advantageous in that only a single solvent will suffice without the necessity for using various solvents according to the respective steps.
    • 制备由通式[Ⅷ]表示的羧酸衍生物的方法(其中R 1,R 2,R 3和L各自如说明书中所定义),其中包括使苄基卤与 氰基化合物,得到苯基乙腈,在碱的存在下使腈与亚硝酸烷基酯反应,得到α-羟基亚氨基苯基乙腈,使羟基腈与烷基化剂反应,得到α-烷氧基亚氨基苯基乙腈,在存在下水解烷氧基腈 的碱,任选地在水合和酸处理之后,得到α-烷氧基亚氨基苯基乙酸,最后使酸与卤化剂反应,或将酸转化成相应的金属盐,并使该盐与烷基化剂反应,或使 在酸性催化剂存在下用低级醇酸化。 根据该方法,可以在温和条件下通过各自的步骤进行反应,即使不使用高压蒸汽设备,高温热介质设备,冰箱等,也可以生产目标衍生物[Ⅷ] 。 此外,该方法的优点在于,仅根据相应步骤仅需要使用各种溶剂即可满足单一溶剂即可。
