Acetic acid (0.3 g) and triethylamine (0.7 ml) are dissolved in ethyl acetate (10 ml), and thereto is added ethyl 2-methanesulfonyloxyimino-2-cyanoacetate (1.1 g) and the mixture is stirred for 40 minutes. To the solution is added aniline (0.5 g) and the mixture is stirred for 2 hours. The reaction mixture is washed well with 1 N aqueous sodium hydrogen carbonate, water and 1 N hydrochloric acid in order and then dried over anhydrous magnesium sulfate. After drying, the solvent is distilled off to give flasks of acetanilide (0.6 g), melting poit: 95°-105° C. The product recrystallized from water has a melting point of 104°-108° C.
