20.4 Parts of triethylamine are added to a stirred mixture of 40.6 parts of nonyl-N-hydroxycarbamate, 100 parts of dioxan and 35.3 parts of benzene sulphonyl chloride at 0° C keeping the pH in the range 2 to 5. The mixture is stirred for 18 hours at 25° C then added to 500 parts of water. The oily product is separated into 300 parts of toluene and the solution is washed with water, dried and evaporated at 40° l C under reduced pressure to give 72 parts of nonyl-N-benzenesulphonyloxycarbamate as a colourless oil.
