These common heterocyclic compound, 755027-18-0, name is 1-Bromo-4-iodo-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. SDS of cas: 755027-18-0
General procedure: To a degassed solution of 1-bromo-4-iodo-2-methoxybenzene (2.2 g, 7.03 mmol), (4-methoxy-2-nitrophenyl)boronic acid (2.1 g, 10.55 mmol) in DME (80 mL) was added Pd(Ph3P)4 (812 mg, 0.7 mmol) and CsF (2.4 g, 15.82 mmol) under nitrogen. The reaction was then heated to 70 C for 18 h. The reaction was then extracted with EtOAc and water. The organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified silica (gradient elution, 3-40% EtOAc/hexanes) to give the title compound (2.7 g, 99%).
The synthetic route of 1-Bromo-4-iodo-2-methoxybenzene has been constantly updated, and we look forward to future research findings.
