Versuchsvorschrift

A solution of 4.45 g of thiazolidine in 100 ml of ether was cooled to about 0° C. and 8.35 g of O,S-dimethyl phosphoroisocyanatidothioate was added dropwise with stirring. The mixture was allowed to warm to ambient temperature and react for about 1 hour at which time the precipitate that formed was collected by filtration. This precipitate was then recrystallized from a small amount of 2-propanol to obtain 3.6 g (28 percent of theory) of the title compound as white crystals melting at 84°-86° C.
