Abstract

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.
