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. 33332-25-1, name is Methyl 5-chloropyrazine-2-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., Application In Synthesis of Methyl 5-chloropyrazine-2-carboxylate
Methyl 5-(chloropyrazine)-2-carboxylate (36 7) (2g, 0.0115mmol) was dissolved in 80mL of 87 DMSO. 88 Sodium azide (3g, 0.0463mmol) and 39 triphenylphosphene (4.6g, 0.1738mmol) were added and the mixture was refluxed at 120C for 4h. 20mL of 1N 89 HCl was added and the reaction was continued at 120C for 2h. The mixture was cooled and neutralized by using 90 aqueous NaHCO3 solution and 91 product was extracted in ethyl acetate, dried using Na2SO4. The ethyl acetate fraction was evaporated and washed with n-pentane to get 0.7g (yield 39.5%) yellow solid of compound 8. 1H NMR (400MHz, DMSO-d6) delta 8.53 (d, J=1.2Hz, 1H), 7.91 (d, J=1.2Hz, 1H), 7.39 (s, 2H), 3.79 (s, 3H). C6H7N3O2 [M]: 153.14; MS (ESI) m/z: [M-H]+: 152.05.
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 33332-25-1.
