Versuchsvorschrift

To a stirred suspension of lithium aluminum hydride (0.01 g., 0.263 mmol) in 1 ml dry tetrahydrofuran at 0° under argon was added dropwise 5-trimethylsilyl-3-furaldehyde (0.09 g., 0.535 mmol). This mixture was allowed to warm to room temperature, stirred for 15 minutes, quenched with a 5% ammonium chloride solution, and extracted twice with ethyl ether. The organic portion was washed with 5% sodium bicarbonate, water, saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated to give the desired alcohol. This material was used without further purification.
