Introduction of a new synthetic route about 4-Chloro-3-fluoroaniline

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Chloro-3-fluoroaniline, and friends who are interested can also refer to it.

Related Products of 367-22-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 367-22-6 name is 4-Chloro-3-fluoroaniline, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

At 0 C, to a mixture of 4-chloro-3-fluoroaniline (7 g, 48.1 mmol) in DCM (100 mL) was added pyridine (7.8 mL, 96 mmol), followed by phenyl carbonochloridate (6.3 mL, 50.5 mmol). The mixture was stirred at 0 C for 1 h, then warmed up to rt overnight. The mixture was washed with IN HCl and back extracted with DCM. The combined organics were washed with brine, dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated to give phenyl (4-chloro-3-fluorophenyl)carbamate (12 g, 45.2 mmol, 94 % yield) as a colorless solid. The crude product was used without further purification.LC/MS (ESI): m/z 266.1 (M+H)+, 1.13 min (ret. time).
