반응 단계

Dodecylmagnesium bromide (a 1M solution in tetrahydrofuran 14.3 ml, 14.3 mmol) was added dropwise to a solution of 2-triethylsilyl-4-furaldehyde (2.0 g, 9.52 mmol) in THF (20 ml) at 0 degrees C under argon. After stirring at room temperature for 2 hours, the mixture was quenched with dilute HCl and extracted with ethyl ether. Evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by flash chromatography on silica using 30% ethyl ether/hexane to give the titled alcohol.
