Synthetic Route of 6574-97-6, A common heterocyclic compound, 6574-97-6, name is 2,3-Dichlorobenzonitrile, molecular formula is C7H3Cl2N, 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.

General procedure: A mixture of a benzonitrile, 3a (310mg, 3mmol), 28 sodium azide (586mg, 9 mmol), and 29 triethylamine hydrochloride (1.24 g, 9 mmol) in 30 toluene (80 mL) was heated to 100°C for 24h with stirring. After cooling, the reaction mixture was extracted with water. Then, 36percent 31 HCl was added dropwise to the aqueous layer. Precipitation occurred, which was filtered off and washed with water to provide 32 4a as white solid (395mg, 90percent). Mp: 214?216°C. 1H NMR (500MHz, DMSO-d6): delta 8.04?7.02 (m, 2H), 7.62?7.57 (m, 3H)

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
