Electric Literature of 151-18-8,Some common heterocyclic compound, 151-18-8, name is 3-Aminopropanenitrile, molecular formula is C3H6N2, 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 1-bromo-3-iodobenzene (4.0 g, 14.1 mmol) in DMSO (40 mL) were added 3-aminopropanenitrile (1.5 mL, 20 mmol) , cuprous iodide (2.8 g, 15 mmol) , cesium carbonate (7.0 g, 21.5 mmol) and N, N-dimethylglycine (1.5 g, 14 mmol) in turn. The mixture was stirred at 70 for 5 h and quenched with water (40 mL) . The resulting mixture was extracted with DCM (40 mL × 3) . The combined organic layers were dried over anhydrous Na2SO4and concentrated in vacuo. The residue was purified by silica gel column chromatography eluted withPE/EtOAc (v/v) 2/1 to give a light yellow oily product (3.0 g, 94) .[0990]MS (ESI, pos. ion) m/z: 225.0, 227.0 [M+1]+
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Aminopropanenitrile, its application will become more common.
