Procedure
mCPBA (85%, 9.9 g, 48.9 mmol) was added to a solution of 7-fluoro-5-vinyl-2-benzofuran-1(3H)-one (2.9 g, 16.3 mmol) in 300 mL of DCM at 0° C. The mixture was stirred at room temperature for 16 hours before being cooled to 0° C. The mixture was washed sequentially with saturated NaHCO3 (50 mL), aqueous Na2SO3 (50 mL×2), 5% NaOH (50 mL) and brine, then concentrated. The residue was purified by column chromatography eluted with DCM to afford 7-fluoro-5-oxiran-2-yl-2-benzofuran-1(3H)-one as white solid.
