Reaktionsschritte
20 g of 4-carboethoxyphenyl isothiocyanate was dissolved in 50 ml of carbon tetrachloride, and 13 g of aminoacetaldehyde diethylacetal was dropwise added thereto in 5 minutes. Then, the resulting solution was stirred at room temperature for 1 hour. 50 ml of carbon tetrachloride was added to the reaction mixture, and crystals precipitated were collected by filtration, washed with 50 ml of carbon tetrachloride, then dried. Yield: 27.5 g (80.9 mol%).
