실험 절차

2.2 g of water are added dropwise at 30 C to 40° C. to a solution of 19.2 g of 2-ethoxyphenoxysulfonyl isocyanate in 150 ml of tetrachloromethane. The mixture is stirred at room temperature until the evolution of carbon dioxide has ceased and cooled to 0° C., the product is filtered off with suction, and the filter residue is washed with ice-cold tetrachloromethane. Drying in vacuo gives 16 g of 2-ethoxyphenyl sulfamate of melting point 62°-65° C.
