To a suspension of 0.55 g of LiAlH4 (13.9 mmol) in THF (10 mL) is added dropwise a solution of 2 g (13.9 mmol) of Compound 17 in THF (10 mL) under nitrogen atmosphere. Upon complete addition, the reaction is stirred at room temperature for 18 h. The reaction is cooled in an ice-bath and quenched with addition of 1M aqueous NH4Cl solution (2 mL). The resulting precipitate is removed by filtration through Celite and is rinsed with ethyl acetate (3¡Á100 mL). The filtrate is dried over Na2SO4, filtered and concentrated under reduced pressure to afford 1.63 g of Compound 18 as a colorless oil.
