Application of 578-57-4, These common heterocyclic compound, 578-57-4, name is 1-Bromo-2-methoxybenzene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A 10 mL vial was charged with CuI (9.5 mg, 0.05 mmol), PSAP (30 mg,0.05 mmol, > 100 mesh), K3PO4 (424 mg, 2 mmol), aryl bromides (1mmol), amines (1.5 mmol), DEG (2 mL), and a magnetic stir bar. The vessel was sealed with a septum and placed into a preheated oil batchat 70 C. The reaction mixture was held at this temperature for 14 hours. After cooling to r.t., the reaction mixture was filtered, and the precipitates were thoroughly washed with water and EtOAc (3 × 20mL). The combined organic phases were washed with water and brine, dried over anhydrous Na2SO4, and concentrated in vacuo. Theresidue was purified using flash column chromatography on silica gel(eluting with petroleum ether/EtOAc) to afford the desired products.
Statistics shows that 1-Bromo-2-methoxybenzene is playing an increasingly important role. we look forward to future research findings about 578-57-4.
