PREPARATIVE EXAMPLE 44; .Ph In aBH4; Step i; A mixture of 3-bromo-6-fluoro-o-xyle?e (25.37g, 432 mmol) in anhydrous CCI4 (250 mL) was treated with NBS (44.5g, 864 mmol) and benzoyl peroxide (310 mg) and then heated at reflux overnight. The mixture was cooled to 0 C and filtered, washing with hexanes. The filtrate was concentrated and chromatographed (hexanes) to give 44A as an colorless oil (41.57g, with minor mono-bromo impurities).
