Reaction Steps

26.6 Parts of butyl N-hydroxycarbamate and 38.1 parts of p-toluenesulphonylchloride are stirred in 100 parts of dioxan maintained at 0° to 5° C. 20.4 Parts of triethylamine are added during 1 hour keeping the pH at 3 to 6. The mixture is then stirred for 18 hours at 25° C and added to 500 parts of water. The oily precipitate is taken up into 200 parts toluene, and the solution is dried, filtered and evaporated to constant weight at 40° C under reduced pressure to give 52 parts of butyl N-p-toluenesulphonyloxycarbamate as a yellow oil.
