Application of 63069-50-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 63069-50-1 as follows.
4-Amino-3-chloro-5-fluorobenzonitrile A mixture of 4-amino-3-fluorobenzonitrile (1 equiv.) and N-chlorosuccinimide (1.5 equiv.) in acetonitrile (0.24 M) was stirred at 85 C. for 5 h. The solvent was removed by concentration and the residue was partitioned between ethyl acetate and 5% NaOH. The organic phase was washed with 5% NaOH and brine. Then the organic phase was dried over MgSO4 and dried in vacuum to afford 4-amino-3-chloro-5-fluorobenzonitrile (88%) as a beige solid. 1H NMR (400 MHz, CDCl3) delta ppm: 7.41 (t, J=6 Hz, 1H), 7.24 (dd, J=1.8, 10.2 Hz, 1H), 4.66 (s, 2H).
According to the analysis of related databases, 63069-50-1, the application of this compound in the production field has become more and more popular.
