Paragraph 0015-0042, (2020/07/02)
The invention discloses a preparation method of 2-methoxy-5-amino-4-methylpyrimidine, and belongs to the technical field of organic chemistry. The method comprises the following steps: carrying out ahydrogenation reaction by taking 2-methoxy-5-nitro-4-methyl-6-chloropyrimidine as a raw material, methanol as a solvent, triethylamine as an acid-binding agent and nickel as a catalyst to generate a mixture of 2-methoxy-5-amino-4-methylpyrimidine and other impurities, filtering, extracting, drying, and freezing to obtain a pure product 2-methoxy-5-amino-4-methylpyrimidine with the yield of 71-86%.According to the preparation method, the defects of the existing synthesis process are overcome, and a new method for synthesizing 2-methoxy-5-amino-4-methylpyrimidine is provided.
