5-Bromo-1,3-dichloro-2-methylbenzene Use and Manufacturing

Preparation 2; 5-bromo- 1 , 3-dichloro-2-methylbenzene; Suspend the 3, 5-dichloro-4-methylaniline in 48percent HBr (5 mL) and water (5 mL) and heat with a heat gun until the mixture is near the boiling point. Cool the slurry to room temperature and then cool to 0Preparation 9; 5-bromo-l, 3-dichloro-2-methylbenzene; Suspend 3, 5 -dichloro-4-methylaniline in 48percent HBr (5 mL) and water (5 mL) and heat with a heat gun until the mixture is near the boiling point. Cool the slurry to room temperature and then cool to 0Preparation 3; 5-bromo-2-(bromomethyl)- 1 , 3-dichlorobenzene; Heat a solution of 5-bromo-l, 3-dichloro-2-methylbenzene (97 mg, 0.40 mmol), N-bromosuccinimide (76 mg, 0.425 mmol) and benzoyl peroxide (16 mg, 0.06 mmol) in CCl4 (5 mL) to reflux for 3 hours under N2. Cool the reaction to room temperature and concentrate to an orange residue. Purify the residue by silica gel chromatography eluting with hexanes to afford 112 mg (87percent) of the product as white crystals.Preparation 10; 5-bromo-2-(bromomethyl)-l, 3-dichlorobenzene; Heat to reflux a solution of 5-bromo-l, 3-dichloro-2-methylbenzene (97 mg, 0.40 mmol), N-bromosuccinimide (76 mg, 0.425 mmol) and benzoyl peroxide (16 mg, 0.06 mmol) in CCl4 (5 mL) for 3 hours under N2.
