25 Parts of triethylamine are added over 30 minutes to a stirred solution of 19.6 parts of acetyl chloride and 50.6 parts of nonyl-N-hydroxycarbamate in 500 parts of ether at 0°-5° C. keeping the pH of the mixture in the range pH3 to pH6. The reaction is stirred for a further 2 hours at 0°-5° C. followed by 24 hours at 25° C. and is then filtered to remove amine hydrochloride. The filtrates are washed with water, dried, filtered and evaporated to constant weight at 30° C. under reduced pressure to give 61 parts of nonyl-N-(acetoxy)carbamate as a pale yellow oil.
