実験手順
1-(4-Bromo-phenyl)-cyclopropanecarboxylic acid ethyl ester (25 g, 92.89 mmol) was dissolved in THF (175 mL) and was stirred under N2 atmosphere at −4° C. Lithium aluminum hydride (4.58 g, 120.75 mmol) was added in portions and the reaction stirred between 2 to 8° C. for 1 hour. The reaction was worked up using the Fieser method, filtered and concentrated to afford the title compound.
