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. 5900-13-0, name is 5-Bromo-3-methoxypyrazin-2-amine, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C5H6BrN3O
Intermediate Example lnt-3: ferf-Butyl {1-[4-(6-bromo-8-methoxy-3-phenylimidazo[1,2-a]pyrazin-2 l)phenyl]cyclobutyl}carbamate A mixture of crude fert-butyl (1-{4-[bromo(phenyl)acetyl]phenyl}cyclobutyl)- carbamate [lnt-1-A] (203 mg, 0.38 mmol, 1.0 eq), 5-bromo-3-methoxypyrazin-2- amine (74.6 mg, 0.38 mmol, 1 eq.; Jiang, B. et al. Bioorg. Med. Chem (2001), 9, 1 149-1154.) and diisopropylethylamine (0.064 ml_, 0.38 mmol, 1.0 eq) in 2.3 ml_ butyronitril was heated to 120 for 17 hours and t o 125 *C for 6h. The reaction mixture was concentrated in vacuo. The crude mixture was purified via preparative HPLC under basic conditions (column: Waters X-Bridge, eluent: ACN/water (15/85) -> ACN/water 55/45) to deliver 9 mg (4%) of the title compound. UPLC-MS (Method 2): RT = 1.62 min; m/z = 549 (M) +.
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 5900-13-0.
