Paragraph 0014; 0018; 0019; 0026; 0027; 0034; 0035, (2017/10/13)
The invention discloses a preparation method of 5-bromine-thiazolo [4,5-D] pyrimidine. The preparation method comprises the following specific steps of by adopting 4-amino-5-thiazolecarboxylate as an initial material, preparing thiazolo [4,5-D] pyrimidine-5,7-glycol through cyclization; preparing thiazolo [4,5-D] pyrimidine-5,7-dibromo from the thiazolo [4,5-D] pyrimidine-5,7-glycol through bromination reaction; and finally preparing 5-bromine-thiazolo [4,5-D] pyrimidine from the thiazolo [4,5-D] pyrimidine-5,7-dibromo through hydrogenation. The method is short in process route, convenient to operate, relatively mild in reaction condition, easy to control, relatively low in cost and suitable for process amplification, and a product is easy to purify and relatively high in yield.
