Some common heterocyclic compound, 6609-56-9, name is 2-Methoxybenzonitrile, molecular formula is C8H7NO, 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: 6609-56-9
General procedure: To a reaction tube charged with NBS (1.5 equiv, 0.3 mmol), catalyst (10 mol%, 0.02 mmol) and CH3CN (1.0 mL),was added para-chloroanisole 1a (0.2 mmol). After being stirred at room temperature for 12 h in dark, the reaction was quenched by saturated aq. solution of Na2S2O3 (2 mL). The resulting mixture was extracted by ethyl acetate (3 5 mL). The combined organic extracts were washed by brine (10 mL), dried over Na2SO4 and filtered through a pad of Celite. The filtrate was concentrated under reduced pressure and the residuewas purified by flash chromatography on a silica gel column with petroleum ether/dichloromethane (5:1) as the eluent to give 4.3.1. 2-Bromo-4-chloroanisole (2a)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6609-56-9, its application will become more common.
