Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
Procedure: Sodium thiomethoxide (1.0 g, 14.3 mmol) and 4-bromobenzyl bromide (2.65 g, 10.6 mmol) were combined with anhyd THF (50 mL) and the reaction mixture was stirred at 60° C. After 3 h the reaction mixture was concentrated in vacuo and the residue was washed into a separatory funnel with EtOAc and water. The organic layer was separated, dried (anhyd MgSO4), and concentrated in vacuo to yield 1-bromo-4-methylthiomethyl-benzene. To a solution of this crude thioether in DCM (100 mL) was added 3-chloroperoxybenzoic acid (77%, 4.0 g) portionwise. After stirring overnight the reaction mixture was poured into a separatory funnel, washed with 1N NaOH, dried (Na2SO4), and concentrated in vacuo. The residue was crystallized from EtOAc-Hex to afford 1-bromo-4-methanesulfonylmethyl-benzene (2.02 g, 76%) as light tan needles: After 3 h the reaction mixture was concentrated in vacuo the residue was washed into a separatory funnel with EtOAc and water The organic layer was separated dried (anhyd MgSO4) concentrated in vacuo
