Procedure
A mixture of 2.57 g of 2-(oxetan-3-oxycarbonyl)phenylsulfonamide, 2.14 g of diphenyl carbonate, 1.38 g of potassium carbonate and 13 ml of dimethylformamide is stirred at a temperature of 20°-25° C. for 15 hours. The reaction mixture is then poured into ice-water, the pH is brought to a value of 5-6 by dropwise addition of 10% hydrochloric acid and the mixture is extracted with ethyl acetate and washed with water. After drying over sodium sulfate, evaporation and crystallisation of the residue from diethyl ether, 2.2 g of phenyl N-[2-(oxetan-3-oxycarbonyl)phenylsulfonyl)carbamate (compound 1.030) of melting point 91°-92° C. are obtained.
