Versuchsvorschrift

To a stirred suspension of lithium aluminum hydride (4.0 g, 0.105 mol) in THF (100 mL) at 0° C. under a nitrogen atmosphere was added a solution of 4-[4-(1,1-dimethylethyl)-phenyl]butanoic acid (10.31 g, 0.0455 mol) in THF (80 mL). The reaction was heated to reflux for 6 hours. The reaction was cooled to 0° C. and water (4 mL), 15% NaOH (4 mL) and water (12 mL) were carefully added. Ethyl ether (150 mL) was added, the mixture warmed to ambient temperature, and the precipitated salts were removed by filtration. Removal of solvent gave 9.15 g of 4-[4-(1,1-dimethylethyl)phenyl]-butanol as a colorless oil.
