실험 절차

A solution of 2-[2-(2,5-dimethylphenoxymethyl)-phenyl]acetonitrile (2.00 g, 8.0 mmol) in N,N-dimethyl-formamide (20 ml) was stirred at 0° C. 60% oily sodium hydride (0.38 g, 9.5 mmol) was added thereto, and then ethyl iodide (1.37 g, 8.8 mmol) was added dropwise over 5 minutes. After 1 hour, water was added, and the mixture was extracted with ethyl acetate, washed successively with water and saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated, and the residue was purified by column chromatography on silica gel (n-hexane/ethyl acetate=19/1) to give the desired compound 2-[2-(2,5-dimethylphenoxymethyl)phenyl]butyronitrile (1.91 g, 86%) as an oil.
