Procedure

1.815 Grams of methyl methylthiomethyl sulfoxide was dissolved in 20 ml of dimethylformamide, and the solution was added with 380 mg of sodium hydride under cooling with ice, and then stirred for 1.5 hours at room temperature. Thereafter, upon addition of 1.515 g of benzonitrile, the mixture was stirred for 1.5 hours at room temperature and for 10 hours at 50°C., followed by addition of 70 ml of methylene chloride and 2 ml of water and stirring for 20 minutes at room temperature. After drying with Glauber's salt and filtration, the filtrate was concentrated under reduced pressure. The resulting product was crystallized from methylene chloride-carbon tetrachloride-cyclohexane to obtain 2.332 g of 1-methylsulfinyl-1-methylthio-2-amino-2-phenylethylene. The isolation yield was 70%.
