Versuchsvorschrift

To a solution of 5.0 g (0.05 m) of ethyl N-hydroxyacetimidate and 8.5 g (0.05 m) of N-chloroacetyl-N-methyl-carbamoyl chloride dissolved in 75 ml of toluene was added 5.05 g (0.05 m) of triethylamine. After stirring for 2 hours the reaction mixture was filtered through a bed of Celite. The filtrate was concentrated under reduced pressure to afford 10.3 g of a light yellow crystalline solid. m.p. 69°-71° C.
