4897-84-1, Adding some certain compound to certain chemical reactions, such as: 4897-84-1, name is Methyl 4-bromobutanoate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4897-84-1.
To a 250 mL flask equipped with a magnetic stirring bar, azepane, anhydrous acetonitrile (20 mL), methyl-4-bromobutyrate and potassium carbonate were added. A slight temperature increase was observed. The mixture was stirred at room temperature and the overall reaction time was 4 days. (0049) As the reaction proceeded, potassium carbonate was gradually consumed as it scavenged the liberated HBr to form potassium bromide (4.8 g) and potassium bicarbonate (4.0 g). (0050) DCM (10 mL) was added and the solid was collected by vacuum filtration. The organic phase was washed with deionized water (10 mL), separated, dried over MgSO4 and filtered, and the solvent was stripped using rotary evaporation. Yield: pale oil, 7.9 g, (>99percent). (0051) Characterization. FTIR: C?O, 1737, C?O, 1177 cm?1. (0052) H+ NMR: (CDCl3) delta ppm 3.67 (s, 3H), 2.61 (t, 4H), 2.48 (t, 2H), 2.34 (t, 2H), 1.77 (q, 2H), 1.62-1.58 (m, 8H).
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 4897-84-1.
