Paragraph 0014; 0016; 0018; 0020; 0022, (2017/07/21)
The invention relates to preparation of one medicine intermediate, in particular relates to a preparation method of 2-aminomethylpyrimidine hydrochloride and derivatives thereof. The preparation method is improved by overcoming the defects of an industrial production technology and a laboratory technology which are commonly used at present, improvements are as follows: the method takes 2-cyanopyrimidine and derivatives thereof as starting materials, Boc anhydride is adopted as a protective agent, reduction-protection one-pot reaction is carried out under alkaline condition, and then hydrogen chloride deprotection is carried out, so that the 2-aminomethylpyrimidine hydrochloride and the derivatives thereof are prepared. According to the method provided by the invention, the reaction period is short, the conversion rate is high, the product quality is good, and the content of the produced 2-aminomethylpyrimidine hydrochloride and the derivatives thereof is more than 99%; meanwhile, operation steps are simple, required equipment is simple, and energy consumption is low.
