以尿素和碳酸二甲酯为原料,甲醇钾为催化剂,通过碳酸二甲酯的氨解反应在常压下合成了标题化合物,产率最高可达98%。采用三因素六水平交叉实验确定了最佳合成工艺条件,通过FT-IR谱和1HNMR谱确认了产物的分子结构。
Using urea and dimethyl carbonate as raw materials and potassium methoxide as catalyst, the title compound was synthesized by aminolysis of dimethyl carbonate at atmospheric pressure with a yield of up to 98%. The optimal synthesis conditions were determined by three-factor and six-level crossover experiments. The molecular structure of the product was confirmed by FT-IR and 1HNMR spectra.
