Paragraph 0025-0048, (2020/04/17)
The method 4, 4, 4- comprises the following steps -2- adding -1-tricitro-butyric acid and,azido-(1)-azidomethyl ethyl ester 20 °C -30 °C to dichloromethane, to obtain 4, 4, 4-nitrobutyric acid 1,3-azidomethyl ethyl ester, by adding ethyl acetate solution, to the yellow oily liquid 25 °C -35 °C and normal pressure to distill the solvent 8h-30h, at normal pressure . ] The solvent 1.(2) is added into the orange turbid liquid 1 under a normal pressure distilled-off solvent, to obtain an orange cloudy liquid -10 °C -0 °C, and a normal pressure distilled-dry type ethyl ester of, ?, ml of n-nitroobutyric acid ethyl ester in an atmospheric pressure distilled from the solvent. 2.(3) . The invention discloses a method -2- for synthesizing 4, 4, 4- 2- nitrobutyric -1- acid-4, 4, 4-azidomethyl -2- ethyl ester by a normal-pressure distilled -1-dry method, of the reaction -10 °C -0 °C, at a temperature.
