Novel intermediates for the production of aminoacetyl pyrrolidine carbonitrile derivatives ensure the safe and efficient production of the compounds. Specifically, the present invention provides a sulfonyloxyacetyl pyrrolidine derivative, represented by the following formula:
(Chemical Formula 1)
(wherein R1 is a substituted or unsubstituted C1-C6 alkyl group, a substituted or unsubstituted C3-C6 cycloalkyl group, a substituted or unsubstituted arylmethyl group, a substituted or unsubstituted aromatic hydrocarbon, a substituted or unsubstituted aromatic heterocyclic ring or a substituted or unsubstituted aliphatic heterocyclic ring; R2 is CONH2 or CN; and X is CH2, CHF or CF2.)
用于生产氨基乙酰吡咯烷碳腈衍生物的新型中间体,确保化合物的安全高效生产。具体而言,本发明提供了一种磺酰氧乙酰吡咯烷衍生物,其表示为以下式子:(化学式1)(其中,R1是取代或未取代的C1-C6烷基,取代或未取代的C3-C6环烷基,取代或未取代的芳基甲基,取代或未取代的芳香碳氢化合物,取代或未取代的芳香杂环环或取代或未取代的脂环杂环;R2为CONH2或CN;X为CH2,CHF或CF2。)
