KBS15: Reduction to ferrocenylmethanol

Method

Ferrocenyl methyl ester KBS14 (396 mg, 1.62 mmol) was dissolved in dry THF (10 mL) under nitrogen and LiAlH4 (2.0 mL, 1 M in THF, 2.0 mmol, 1.23 equiv.) was added dropwise. The reaction was stirred for 3 hours before being quenched with ethyl acetate (15 mL) and poured over Rochelle's salts (40 mL, sat.). The mixture was extracted with ethyl acetate (40 mL x 4) and washed with brine (100 mL). The organic extract was dried over MgSO4 and concentrated under reduced pressure to yield a reddish-orange solid (332 mg, 95%).
