Versuchsvorschrift

To a suspension of lithium aluminum hydride (3 g) in dry ether (300 ml) was added a solution of ethyl 2-((E)-4-methoxybenzylidene)butyrate (19 g) in dry ether (30 ml) at 0° C. with stirring. The mixture was stirred at the same temperature for 3 hours and excess lithium aluminum hydride was decomposed with wet ether. The reaction mixture was filtered and the filtrate was washed with water, dried over magnesium sulfate and then evaporated to dryness to give 2-((E)-4-methoxybenzylidene)butan-1-ol (13 g).
