11.4 parts of 2-oxo-4-iminothiazolidine are stirred with 15 parts of 1,3-diiminoisoindoline in 300 parts of water for 40 hours at about 25° C., whilst passing a slight stream of nitrogen over the mixture. The product is then filtered off and washed with water, giving 22 parts of 1-imino-3-(2'-oxo-4'-iminothiazolidinylidene)-isoindoline (Formula II, Z=>O), the spectroscopic properties of which correspond to those of the product obtained as described in Example 11.
