Versuchsvorschrift

A reaction vessel was charged with lithiumaluminium hydride (0.433 g, 11.41 mmol) and dry diethyl ether (20 mL). After cooling to 5° C. a solution of 2-(4-methoxyphenyl)-2-methylpropanenitrile (2.00 g, 11.41 mmol) in dry diethylether (10 mL) was added dropwise. The reaction mixture was stirred at 5° C. for 2 h. The reaction mixture was then cooled in an ice bath and 2N aqueous sodium hydroxide solution (0.8 mL) and water (1.5 mL) were added. After stirring for 20 min additional water (40 mL) was added and the reaction mixture was extracted with ethyl acetate (2×30 mL). The combined extracts were dried (MgSO4) and the solvent was evaporated in vacuo. The crude product (1.94 g, 10.82 mmol) was used without further purification for the next step.
