2-Bromo-1-bromomethyl-5-chlorobenzene Use and Manufacturing

20.5 g (100 mmol) of 2-bromo-5-chlorotoluene was dissolved in 200 ml of carbon tetrachloride, 0.2 g (1 mmol) of AIBN and 19.6 g (110 mmol) of N-bromosuccinimide were added thereto, the resulting mixture was refluxed for 2 hours and cooled to room temperature. The reaction mixture was washed with 50 ml of water twice and with 50 ml of a brine solution, dried over anhydrous MgS04, and distilled under a reduced pressure to obtain an oil containing a small amount of the starting material. The oil was dissolved in 20 ml of hexane, and recrystallized at room temperature to obtain ' 22.7 g (yield 80percent) of 2-bromo-l-bromomethyl-5-chlorobenzene. Step 1: l-bromo-2-(bromomethyl)-4-chlorobenzene; l-bromo-2-(bromomethyl)-4-chlorobenzene was prepared according to literature precedent (J. Am. Chem. Soc. 2002, 124 (7), 1354): a suspension of l-bromo-2-methyl-4-chlorobenzene (1 eq), NBS (1 eq) and benzoyl peroxide (0.004 eq) in CCl
