Aluminium lithium hydride → HCID 86602918, compound

Participants

Reaction Steps

The compound (32.6 g, 30.3 mol) synthesized in Example 2 (2d) was dissolved in diethyl ether (600 mL) and lithium aluminium hydride (1.72 g, 45.4 mol) was added thereto, followed by heating of the mixture under reflux for 1 hour. After the reaction mixture was diluted with diethyl ether (200 mL), 1N aqueous NaOH solution (2.0 mL) and water (2.0 mL) were added thereto, followed by stirring of the mixture for 30 minutes. After celite filtration, the solvent was distilled off under reduced pressure. The residue was purified using silica gel flash column chromatography (hexane:ethyl acetate, 7:1-6:1, V/V) to obtain the desired title compound (15.0 g, yield 55%) as a colorless solid.
