Versuchsvorschrift

5 g N-butyl-carbamic acid benzoic acid sulfimide are suspended in the mixture of 1.67 g of phenol and 50 ml of water, then while stirring (5 hours), a solution of 0.71 g of sodium hydroxide in 50 ml water is added. After stirring another 3 hours, the mixture is extracted with 2×30 ml of ether. The ethereal extracts are dried with sodium sulfate, then the solvent is evaporated in a vacuum at a temperature not above 30° C. 2.15 g of phenyl N-butyl-carbamate are obtained, which can be distilled at 146°-148° C. at 2 mmHg.
