Synthesis method | Use 2-amino -3-nitro -5-bromopyridine as the starting material to prepare the target compound 2, 3-diamino -5-Bromopyridine is a typical reduction reaction. The target product is prepared by reducing the nitro group. Due to the low reduction reaction efficiency, there are many reduction wastes, and the post-treatment is complicated, therefore, it is not an ideal preparation route. However, the starting material is easy to obtain, and the target compound prepared by one-step reaction also has its advantages. In this paper, the reaction conditions are optimized by investigating the reduction process, and the catalytic hydrogenation of Raney Ni is used in the reduction process, and the purity of the product is high. The synthesis reaction formula is as follows: |
