実験手順

A solution of methyl benzofuran-7-carboxylate (5.34 g, 30 mmol) was added to a suspension of LAH (2.31 g, 61 mmol) in THF and then heated to reflux for 30 min. The reaction was quenched with ethyl acetate and water. The mixture was made acidic with 12 N HCl until all the precipitate dissolved. The ethyl acetate layer was separated, washed with water, dried with brine, and concentrated in vacuo to give a yellow oil (4.03 g, 91%).
