Dimethyl sulfoxide (2 ml) and 95% sodium cyanide (0.21 g, 0.004 mol) were added to 2-(2,5-dimethylphenoxymethyl)-α-methoxyiminobenzyl chloride (0.60 g, 0.002 mol), and the mixture was stirred at 110° C. for 2 hours. After completion of the reaction, ether (100 ml) was added, and the mixture was washed with water twice, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give 2-(2,5-dimethylphenoxymethyl)-α-methoxyiminophenylacetonitrile (0.45 g, 76.4%) as colorless crystals.
