Synthetic Route of 89364-04-5 , The common heterocyclic compound, 89364-04-5, name is 3-Bromo-4-nitropyridine, molecular formula is C5H3BrN2O2, 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: In a glovebox, K3PO4 (10 mol %, 5.3 mg), 18-Crown-6 (20 mol %, 13.2 mg) , and 2.5 mL tetrahydrofuran were added into a Schlenk tube equipped with a stir bar, then thiol (0.25 mmol) and nitrobenzene derivative (0.25 mmol) were added on the outside under an air atmosphere. The reaction mixture was stirred at room temperature 3 h (450 rpm). The resultant solution was concentrated and purified by silica gel column chromatography with EtOAc and petroleum ether as the eluent to give the corresponding thioether.
The synthetic route of 89364-04-5 has been constantly updated, and we look forward to future research findings.
