Synthetic Route of 887581-09-1,Some common heterocyclic compound, 887581-09-1, name is (2-Bromo-5-methoxyphenyl)methanamine, molecular formula is C8H10BrNO, 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 25 mL Schlenk tube wascharged with a magnetic stirrer and DMSO (2.0 mL). Substituted(2-bromophenyl)methylamine (1) (0.5 mmol), amidine hydrochloride (2) (1.0 mmol),CuBr (0.1 mmol, 14.2 mg), and K2CO3 (1.5 mmol, 207 mg) were added to the tube.The mixture was stirred at 80-120 oC under nitrogen atmosphere for 24 h, and thenunder air for 0.5 h. The resulting mixture was cooled to room temperature and filtered,and the solid was washed with ethyl acetate for two times (3 × 3 mL). The combinedfiltrate was concentrated by the rotary evaporator, and the residue was purified bycolumn chromatography on silica gel using petroleum ether/ ethyl acetate as eluent togive the desired target product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (2-Bromo-5-methoxyphenyl)methanamine, its application will become more common.
