Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 63744-22-9, name is 6,8-Dibromoimidazo[1,2-a]pyrazine, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C6H3Br2N3
Intermediate Example 10-1 : Preparation of 6,8-dibromo-3-iodo-imidazo[1 ,2- ajpyrazineTo a stirred solution of intermediate example 9-1 (8.7 g g, 31.4 mmol) in DMF (210 mL) was added NIS (7.42 g, 33 mmol, 1 .05 eq) in one portion at rt. After 18 h stirring at 60C, the solvent was removed in vaccuo and the residue was taken up in DCM and washed with water and saturated sodium thiosulfate solution. The organic phase was dried over sodium sulphate, filtered and the solvent was evaporated to yield 9.46 g (74.8 %) 6,8-Dibromo-3-iodo-imidazo[1 ,2-a]pyrazine: 1H- NMR (300 MHz, CDCb): delta = 8.22 (1 H, s), 7.91 (1 H, s) ppm.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 63744-22-9.
