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. 87486-34-8, name is 3,5-Dibromo-1-methylpyrazin-2(1H)-one, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C5H4Br2N2O
A solution of tert-butyl 4-(4-aminobenzoyl)piperazine-1-carboxylate (2d, 1.7 g, 5.7 mmol, 1 equiv.), 3,5-dibromo-1-methylpyrazin-2(1H)-one (2e, 1.8 g, 6.8 mmol, 1.2 equiv.) and N,N-diisopropylethylamine (1.48 mL, 8.5 mmol, 1.5 equiv.) in N,N-dimethylacetamide (5 mL) was stirred in a sealed vial at 105 oC for 30 h. The reaction was cooled to room temperature and EtOAc (20 mL) was then added. The solid precipitate was filtered and dried on high vacuum overnight to provide tert-butyl 4-(4-((6-bromo-4-methyl-3-oxo-3,4- dihydropyrazin-2-yl)amino)benzoyl)piperazine-1-carboxylate 2f. The product was carried onto the next step without further purification.
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 87486-34-8.
