実験手順

To a solution of 4-hydroxyphenylpropanenitrile (5.25 g) in N,N-dimethyl formamide (40 mL), 3-phenylpropyl bromide (7.1 g) and potassium carbonate (14.79 g) were added, followed by stirring at room temperature for 16 hours. Then, the reaction mixture was diluted with diethyl ether and an organic layer was successively washed with water and brine. After the organic layer was dried, the solvent was concentrated and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1) to give the title compound (8.54 g) having the following physical properties.
