N-bromobutanimide → Methyl 2-bromo-2-(3-fluorophenyl)acetate

Participants

Reaction Steps

Methyl 2-(3-fluorophenyl)acetate (1.90 g, 11.3 mmol) and N-bromo succinimide (2.01 g, 11.3 mmol) are dissolved in CCl4 (80 mL). HBr (64 ul, 0.56 mmol) is added and the mixture is stirred under reflux overnight. The mixture is cooled at RT, diluted with DCM and washed with sat. NaHCO3, water and brine. The organic layer is dried (Na2SO4), filtered and evaporated obtaining intermediate I144 as a yellow oil (2.68 g, 96% yield).
