Procedure
3,82 g (30 moles) of 2-cyanimino-thiazolidine, 4.9 g (30 mmoles) of 4-chlorobenzyl chloride and 4.3 g of anhydrous potassium carbonate are boiled in 100 ml of acetone for 5 hours. The inorganic salt is filtered off and the acetonic solution is evaporated. The residue is crystallized from 40 ml of isopropanol to yield 6.26 g (83%) of 2-cyanimino-3(4-chlorobenzyl)-thiazolidine, melting at 131° to 133° C. The product is isolated by filtration.
