3,4-dimethoxyphenylacetonitrile (purchased from Tokyo Kasei), 1.77 g (10.0 mmole), and 1.41 g (10.0 mmole) of 3-chlorobenzaldehyde (purchased from Tokyo Kasei) were dissolved with heating into 10 ml of ethanol (purchased from Kokusan Kagaku), two drops of a 20% sodium hydroxide solution were added thereto, the mixture was stirred overnight, and deposited crystals were filtered, washed with ethanol twice and subsequently with hexane twice and dried to obtain 2.35 g (yield: 78.3%) of α-cyano-3'-chloro-3,4-dimethoxystilbene (yellow crystal).
