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. 59489-71-3, name is 2-Amino-5-bromopyrazine, This compound has unique chemical properties. The synthetic route is as follows., HPLC of Formula: C4H4BrN3
5-Bromopyrazin-2-amine (0.11g, 0.63 mmol) was dissolved in NaOMe/MeOH (0.23g Na metal in 10 ml_ MeOH) and heated by microwave irradiation at 14O0C for 7 hours. After evaporation of the solvent, the residue was purified by preparative TLC, eluting with 30% ethyl acetate – n-hexane, to give 5-methoxypyrazin-2-amine (25 mg, 32%).1H NMR (500 MHz, MeOD) delta 7.64 (1H, s), 7.58 (1H, s), 3.85 (3H, s). LCMS (3) Rt 1.75 min; m/z (ESI+) 126 (MH+).
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 59489-71-3.
