Reaction Conditions:
with chloroformic acid ethyl ester;potassium carbonate in chloroform;water at 20 - 30; for 0.25 h;
Steps:
3 Example 3
The inner salt was added to 300 ml of chloroform.141 g of ethyl chloroformate was slowly added dropwise.Control the temperature at 20 °C,After the addition is complete, the temperature is slowly added dropwise at 20°C151.8g aqueous potassium carbonate,After the completion of the dropping, the temperature is raised to 30°C and the temperature is kept for 15 minutes.Layered,The organic phase was concentrated to give the isothiocyanate with a yield of 91.5% and a liquid phase purity of 98.9%.
