3-Bromobenzyl bromide Use and Manufacturing

Methods of Manufacturing

General procedure: To a mixture of NXS and substrate (1 or 6) in CHA mixture of 3-bromotoluene (42.8 g, 0.25 mol), N-bromosuccinimide (48.9 g, 0.275 mol) and benzoyl peroxide (0.75 g) in tetrachloromethane (500 mL) was stirred and heated to reflux for 3 h. The mixture was left to stand overnight at laboratory temperature, the solid was filtered off, washed with tetrachloromethane and the filtrates were evaporated. The residue was distilled in vacuo to yield 52.7 g (62.5percent) of 1-bromo-3-bromomethylbenzene, b.p. 135-140° C./1.6 kPa.{4-[2-(2-Bromo-10, 11-dihydro-dibenzo [a, d]cyclohepten-5-ylidene)-ethylsu Ifanyl]-2-methyl- phenoxy} -acetic acid; A mixture of 3-bromotoluene (42.8 g, 0, 25 mol), N-bromosuccinimide (48.9 g, 0.275 mol) and benzoyl peroxide (0.75 g) in tetrachloromethane (500 mL) was stirred and heated to reflux for 3 h.
