Preparation method of 2-amino-4,6-dimethoxypyrimidine

A preparation method of 2-amino-4,6-diamino-1,3,4-triazole comprises the following steps: malononitrile and methanol which are used as raw materials undergo a hydrogen chloride aeration reaction in asolvent which is one of methylbenzene, dimethylbenzene, chlorobenzene and dichloroethane to generate 1,3-dimethoxypropylenediamine dihydrochloride, a water-insoluble quaternary amine organic alkali isdropwise added into the obtained reaction system without filtration or other post-treatment operations in order to regulate the pH value of the reaction system to 6-8, a cyanamide solid is added, a reaction is performed to generate 3-amino-3-methoxy-N-nitrile-2-propylamidine, and the 3-amino-3-methoxy-N-nitrile-2-propylamidine is heated to react to generate the 2-amino-4,6-dimethoxypyrimidine product. The method for preparing the 2-amino-4,6-dimethoxypyrimidine by using a one-pot process has the advantages of mild reaction conditions, safety, environmental friendliness, process operation simplification, and small amount of three wastes, makes the total synthesis yield of the four-step reaction reach 80% or above and the product content reach 99% or above, and is suitable for green industrial production.
