2-甲基磺酰-4,6-二甲氧基嘧啶的合成

Synthesis of 4,6-Dimethoxy-2-methylsulfonylpyrimidine

以硫脲和丙二酸二乙酯为初始原料合成2-甲基磺酰-4,6-二甲氧基嘧啶,其合成路线新颖、简便。2-甲基磺酰-4,6-二甲氧基嘧啶是农药合成的重要中间体,特别在绿色农药新品种2-(4,6-二甲氧基)嘧啶氧基-N-芳基苄胺衍生物的合成中。

4,6-Dimethoxy-2-methylsulfonylpyrimidine was synthesized using sulphur urea and diethyl malonate as raw materials. The process was novel and simple. It is an important intermediate, especially for the preparation of 2-(4,6-dimethoxy)-pyrimidyloxy -N-het/aryl-benzylamine derivatives, a green novel pesticide.
