Reaction Steps

A solution of 5-fluorobenzofuran-3-ylacetic acid (4.6 g, prepared as described in Example 2) in dry tetrahydrofuran (200 mL) was added dropwise to a suspension of lithium aluminium hydride (4.5 g) in dry tetrahydrofuran (150 mL) at room temperature. After reflux for 2 h the reaction was quenched by successive additions of water (9.2 mL), 15% aq. sodium hydroxide (4.6 mL), water (23 mL). Filtration and removal of solvent in vacuo gave an oil, 2-(5-fluorobenzofuran-3-yl)ethanol (4.3 g).
