Paragraph 0032; 0036; 0037; 0052, (2018/11/03)
The invention discloses a method for preparing 2-amino-3-hydroxymethylpyridine, and belongs to the field of chemical synthesis. 2-aminopyridine and pivaloyl chloride are used as initial reactants to form intermediate product 2-pivalamidopyridine under the action of triethylamine, after hydrogen extraction by use of n-butyllithium, dimethylformamide is added for hydroformylation, and target product2-amino-3-hydroxymethylpyridine can be obtained by reduction with sodium borohydride. Raw materials used in the method are low in cost, and the method is simple in operation, short in synthesis process, mild in reaction conditions, high in yield, and suitable for large-scale industrial production.
