Some common heterocyclic compound, 27060-75-9, name is 1-Bromo-4-methoxy-2-methylbenzene, molecular formula is C8H9BrO, 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. Application In Synthesis of 1-Bromo-4-methoxy-2-methylbenzene
General procedure: In a microwave tube were added a suspension of Pd(dba)2 (5mol%), tBu3PHBF4 (10mol%), NaOH (2eq), aryl bromide (1.2eq) and alpha-tetralone (1.0eq) in a mixture of degassed dioxane/water (4:1, v/v, 2-4mL) and heated under Ar and microwave irradiation (100W of initial power, 100C, 60min, infrared probe). Then, the mixture was allowed to cool to rt, diluted in AcOEt, washed with saturated NH4Cl solution, dried over anhydrous MgSO4, filtered and concentrated under reduced pressure. The crude material was purified by silica gel column with n-hexane:AcOEt (95:5) as solvent.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 27060-75-9, its application will become more common.
