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 21423-84-7 as follows. Computed Properties of C8H6ClN
To a solution of 2-chloro-4-methylbenzonitrile (1 .06 g, 7 mmol) and /V-bromosuccinimide (1 .37 g, 7.7 mmol) in acetonitrile (70 ml_) was added 2,2-azob/s(2-methylpropionitrile (0.230 g, 1 .4 mmol) under argon. The mixture was stirred at 80 C for 20 h. The reaction mixture was filtered and washed with ethyl acetate (80 ml_). The filtrate was concentrated, and the resulting crude material was purified by column chromatography (silica gel, petroleum ether/ethyl acetate = 10/1 ) to give 4-(bromomethyl)-2-chlorobenzonitrile as a light-yellow solid (0.661 g, 2.87 mmol, 41 %). 1 H NMR (400 MHz, Chloroform-d) d 7.67-7.69 (m, 1 H), 7.57-7.58 (m, 1 H), 7.41 (dd, J/ = 1 .5 Hz, J2= 8.0 Hz, 1 H), 4.454 (s, 2H).
According to the analysis of related databases, 21423-84-7, the application of this compound in the production field has become more and more popular.
