Reaction Steps

To an ice cold solution of 2-allyl-4-fluorophenol (853) (6.0 g, 36.2 mmol) in CHCl3 (180.0 mL) was added slowly the suspension of 77% 3-chloroperoxybenzoic acid (8.1 g, 36.2 mmol) in CHCl3 (36.2 mL). The resulting mixture was stirred at 0° C. for 2 hours, then washed with NaHCO3 (100 mL), water (2×100 mL), brine (100 mL) and dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (30-40% EtOAc in hexanes) to provide the desired product (5-fluoro-2,3-dihydrobenzofuran-2-yl)methanol (854) (3.8 g, 57.7%) as a yellow oil.
