Tributylphosphine → HCID 66696256, compound

Participants

Reaction Steps

To a solution of 3 g of methyl 4-fluoro-2-hydroxybenzoate in 60 mL of tetrahydrofuran were added 1.98 g of tetrahydrofuran-3-ylmethanol and 4.28 g of tributylphosphine, followed by ice-cooling. To a mixture was gradually added 6.67 g of 1,1′-(azodicarbonyl)dipiperidine, followed by stirring for 20 minutes. The mixture was warmed to room temperature, stirred for 16 hours, and then poured into a mixture of water and ethyl acetate. The aqueous layer was separated, the organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane/ethyl acetate) to obtain 3.14 g of methyl 4-fluoro-2-(tetrahydrofuran-3-ylmethoxy)benzoate.
