Aluminium lithium hydride → HCID 23288917, compound

Participants

Reaction Steps

A mixture of 3-(isochroman-1-yl)propionic acid (LXXXVII, 0.5054 g, 2.45 mmol) in THF (2.8 ml) is added to an ice-cooled slurry of lithium aluminum hydride (0.1021 g, 2.69 mmol) in THF (3 ml). After the mixture had stirred for 30 min at 0°, it is quenched slowly with water (0.10 ml) water and allowed to stir for 15 min. An aqueous sodium hydroxide solution (15%, 0.10 ml) is added and again the reaction stirred 15 min. After a final addition of water (0.3 ml) the solids are removed by filtration and washed with ether. The filtrate is washed with saline, dried over magnesium sulfate and concentrated to dryness. The crude product is chromatographed on silica gel eluting with methanol/dichloromethane (2/98). The appropriate fractions are pooled and concentrated to give 3-(isochroman-1-yl)propanol (LXXXVIII), NMR (CDCl3) 1.73, 1.92, 2.11, 2.34, 2.68, 3.03, 3.66, 3.78, 4.17, 4.82 and 7.15 δ.
