Versuchsvorschrift
A solution of 0.043 mole of 2-imino-3-methylthiazolidine and an equimolar amount of phenylisothiocyanate in 70 ml of dry benzene is refluxed under nitrogen for 2.5 hours. Some ether is added to the cooled reaction mixture and solids are filtered off, 9.8 g (90%). Recrystallization from acetonitrile-ether (1:1) gives 8.0 g (75%) of pure N-(3-methyl-2-thiazolidinylidene)-N'-phenylthiourea; m.p. 168.5°-170.5° C.
