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 52548-00-2 as follows. Safety of 1-Bromo-4-fluoro-2,3-dimethylbenzene
6-Bromo-3-fluoro-o-xylene (5.00 g, 24.6 mmol) was dissolved in 75 mL carbon tetrachloride. N-Bromosuccinimide (8.76 g, 49.2 mmol) and benzoyl peroxide (0.089 g, 0.37 mmol) were added and the resulting white suspension was refluxed for 18 h. The reaction mixture was filtered and the filtrate concentrated to an oily suspension. The residue was purified by column chromatography on silica gel (eluting with hexanes) and concentrated to give 1-bromo-2,3-bis(bromomethyl)-4-fluorobenzene (8.40 g, 94% yield) as a colorless oil. 1H NMR (400 MHz, CDCl3, ppm) delta 7.55 (dd, J=8.9, 5.2 Hz, 1 H), 6.97 (t, J=8.9 Hz, 1 H), 4.78 (s, 3 H), and 4.67 (s, 3 H).
According to the analysis of related databases, 52548-00-2, the application of this compound in the production field has become more and more popular.
