Sodium Methoxide → 1-Bromo-2-methoxy-4-(methylsulfonyl)benzene

Participants

Reaction Steps

To a solution of 1-bromo-2-fluoro-4-(methylsulfonyl)benzene (Preparation 14, 1.5 g, 5.93 mmol) in MeOH (12 mL) was added sodium methoxide (480 mg, 8.89 mmol) and the reaction mixture was irradiated at 100° C. in the microwave for 1.5 hours. After this time the reaction was quenched with water (50 mL) and the product was extract with EtOAc (3×50 mL). The combined organic layers were dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography eluting with 20-40% EtOAc in heptane to afford the title compound as colourless solid in 53% yield.
