Provided herein is a novel and useful process for preparing 2-methoxy-4-methyl-6-methylamino-1,3,5-triazine that broadly comprises the steps of (a) reacting zinc bis(imino-bis-carbimic acid methyl ester) with acetic anhydride to give 2,4-dimethoxy-6-methyl-1,3,5-triazine and (b) reacting the 2,4-dimethoxy-6-methyl-1,3,5-triazine, formed in step (a), with methylamine to give 2-methoxy-4-methyl-6-methylamino-1,3,5-triazine.
本文提供了一种新颖而有用的制备2-甲氧基-4-甲基-6-甲氨基-1,3,5-三嗪的方法,其广泛包括以下步骤:(a)将锌双(亚胺基-双卡比酸甲酯)与乙酸酐反应,得到2,4-二甲氧基-6-甲基-1,3,5-三嗪;(b)将步骤(a)中形成的2,4-二甲氧基-6-甲基-1,3,5-三嗪与甲胺反应,得到2-甲氧基-4-甲基-6-甲氨基-1,3,5-三嗪。
