Related Products of 923282-39-7 ,Some common heterocyclic compound, 923282-39-7, molecular formula is C6H5ClN4, 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.

To a solution of 2-[3-methoxy-4-[[2-(trifluoromethyl)-4-pyridyl]oxy]phenyl]ethanamine (0.39 g, 1.2 mmol) in acetonitrile (30 mL) was added triethylamine (1.5 g, 4.8 mmol). The solution was stirred for 5 min at room temperature at which time 7-chloro-1-methyl-pyrazolo[4,3-d]pyrimidine (0.25 g, 1.2 mmol) was added. The reaction mixture was stirred at room temperature overnight. Water was added and was extracted with ethyl acetate (3*). The combined organic layers were washed with water, dried over Na2SO4 and concentrated in vacuo. The residue was purified by HPLC to provide 85 mg (0.19 mmol, 17%) of the product.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,923282-39-7, its application will become more common.
