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. 912773-24-1, name is 6-Bromoimidazo[1,2-a]pyrazine, This compound has unique chemical properties. The synthetic route is as follows., category: Pyrazines
A 20 mL Biotage microwave vial loaded with 6-bromoimidazo[1,2-a]pyrazine (1.188 g, 6 mmol) was dissolved in DCM (15 mL), and N-chlorosuccinimide (881 mg, 6.60 mmol) was added in portions, and the mixture was sealed and stirred at 50 C. for 18 h. The vial was diluted with DCM and 10% NaOH, then extracted multiple times with DCM, washed with 10% NaOH, H2O, brine, and the organic layer was dried over Na2SO4, concentrated, dryloaded onto silica gel and purified on a 12 g silica gel column (hexanes/EtOAc, 0-25%), affording 6-bromo-3-chloroimidazo[1,2-a]pyrazine 67-A as a white solid (916 mg, 3.94 mmol, 66% yield, 25% EtOAc in hexanes). 1H NMR (DMSO) delta: 8.98 (d, J=1.3 Hz, 1H), 8.77 (d, J=1.3 Hz, 1H), 8.01 (s, 1H). 13C NMR (DMSO) delta: 143.03, 139.15, 134.20, 123.70, 117.92, 112.33.
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 912773-24-1.
