Participants

Reaction Steps

To a solution of (5-fluoro-2,3-dihydrobenzofuran-2-yl)methanol (854) (1.0 g, 6.0 mmol) in dimethylformamide (130.0 mL) was added 60% NaH in mineral oil (0.480 g, 12.0 mmol) and MeI (1.12 mL, 18.0 mmol). The suspension was stirred at room temperature for 24 h and diluted with water (50 mL), and extracted with ethyl acetate (2×25 mL). The organic layers were combined, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by chromatography (0-10% EtOAc in hexanes) to provide the desired 5-fluoro-2-(methoxymethyl)-2,3-dihydrobenzofuran (855) (0.650 g, 59.5%) as a colorless oil.
