Participants

Reaction Steps

A solution of (2,3-dihydrobenzofuran-5-yl)acetic acid (4.9 g--see EP-A-132130) in anhydrous tetrahydrofuran (50 ml) was added over 10 minutes, dropwise, to a stirred suspension of lithium aluminum hydride (1.57 g) in anhydrous tetrahydrofuran (50 ml) at 0°. The mixture was allowed to warm to room temperature and stirred for 1 hour. Water (1.5 ml) was then added dropwise with caution followed by 10% aqueous sodium hydroxide (1.5 ml) and, finally, water (4.5 ml). The mixture was filtered and the inorganic salts washed with ethyl acetate (2×50 ml). The filtrate and washings were combined and concentrateed in vacuo to give the title compound as an oil, yield 3.3 g.
