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. 1117-71-1, name is Methyl 4-bromobut-2-enoate, This compound has unique chemical properties. The synthetic route is as follows., Application In Synthesis of Methyl 4-bromobut-2-enoate
Trithylamine (37.5 ml, 0.27 mol, 2.8 equiv) was dissolved in THF (100 ml), and dimethylamine hydrochloride (9.3 g, 0.114 mol, 1.2 equiv) was added. Methyl 4- bromocrotonate (2Og, 85% purity, 0.095 mol, 1.00 equiv) in 100 ml of THF was added drop- wise to the resulting solution at room temperature while stirring. The reaction mixture was allowed to react overnight at room temperature. The reaction mixture was filtered, and the filtrate was evaporated under reduced pressure to give yellow oil. The oil was dissolved in 50 ml of isopropanol, and hydrogen chloride was added until pH 2.0 was reached. The white solid was formed and filtered and dried to give 7.1g product. MS (ESI) m/z: 563 (M+l).
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 1117-71-1.
