Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 102151-33-7, name is 3-Chloro-4-methoxybenzonitrile, A new synthetic method of this compound is introduced below., Quality Control of 3-Chloro-4-methoxybenzonitrile
To a solution of 3-chloro-4-methoxybenzonitrile (500 mg, 3.30 mmol) in 10 ml ethanol was added hydroxylammonium chloride (311 mg, 4.0 mmol) and triethylamine (392 mg, 4.0 mmol) and then the reaction mixture was stirred 16 h at 50 C. After cooling to RT, the solvent was evaporated and the crude – – was solved in ethyl acetate and dichloromethane and extracted with water. The organic phase was dried over magnesium sulfate, filtered and evaporated under vacuum to yield the title compound (124 mg, 19 % of theory). LC-MS (method 3B): RT = 0.79 min, m/z = 201 (M+H)+
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.
