Sodium borohydride → 4-Hydroxymethyl-2-triethylsilylfuran

Participants

Reaction Steps

Sodium borohydride (353 mg, 0.93 mmol) was added portionwise to a solution of 2-triethylsilyl-4-furaldehyde (1.64 g, 7.79 mmol) in methanol (10 ml) at 0°. After 1 hour, most of the methanol was evaporated and the residue dissolved in a minimum amount of dilute hydrochloric acid. Extraction (ethyl acetate), drying (magnesium sulfate) and evaporation gave an oil, which was purified by flash chromatography on silica using 20% ethyl ether/hexane. Fractions with Rf of about 0.07 (10% ethyl ether/hexane) gave after evaporation the title alcohol as a colorless oil.
