Method for synthesizing 2,4-diamino-6-chloropyrimidine

The invention discloses a method for synthesizing 2,4-diamino-6-chloropyrimidine. According to the method, methyl cyanoacetate, guanidine nitrate and sodium methoxide serve as raw materials to react with one another to obtain 2,4-diamino-6-hydroxypyrimidine, and then 2,4-diamino-6-hydroxypyrimidine is chloridized with POCl3 in the presence of triethylamine to obtain 2,4-diamino-6-chloropyrimidine.Compared with the prior art, the situation that the whole reactant is neutralized to generate and precipitate a large amount of phosphate is avoided, the product purity is improved, the product yieldis increased, the situation that a solvent is used for refining DACP is avoided, the process is greatly simplified, the cost is reduced, the yield is increased, and the method has the advantages of being high in yield, easy to operate and high in safety and is a very effective process suitable for industrialized mass production.
