Versuchsvorschrift

LiAlH4 (1.0M solution in hexane 1.14 ml, 1.14 mmol) was added dropwise to a solution of ethyl-4-phenyl-3-furoate (246 mg, assumed 1.28 mmol) in tetrahydrofuran (20 ml) at 0 degrees under argon. The solution was stirred and was allowed to warm to room temperature gradually over 1/2 hour. The mixture was quenched with saturated ammonium chloride and the organics were extracted into ethyl ether, and washed with H2O . Evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by flash chromatography on silica using 20% ethyl acetate/hexanes. This was further purified by recrystallation (hexane/ethyl ether) to give the title compound as pale yellow crystals.
