Reaction Steps

To a suspension of lithium aluminium hydride (3.56 g, 94 mmol) in dry ether (100 ml) was added dropwise a solution of the compound (1) (10.9 g, 72 mmol) in dry ether (600 ml) under ice-cooling. The mixture was stirred under ice-cooling for 30 minutes, and thereto was added ethyl acetate and water in that order. The aqueous layer was neutralized with diluted hydrochloric acid and extracted with ether. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by column chromatography on silica gel to give the title compound (2). Yield 7.63 g (77%).
