Versuchsvorschrift

To a stirred solution of 61 parts of 28 percent aqueous ammonium hydroxide solution and 2500 parts of water under at atmosphere of nitrogen there was simultaneously added at ambient temperature during a period of ninety minutes 273 parts of 2,4-diiminothiazolidinium benzenesulfonate and 853 parts of a 17.1 percent by weight methyl alcohol solution of 1,3-diiminoisoindoline. A yellow solid separated during the addition. Stirring was continued at room temperature for approximately sixteen hours after the additions were complete and the thick yellow reaction slurry was then filtered. The product collected on the funnel was washed copiously with distilled water and finely dried at 50° C in vacuo to obtain 233 parts of 1-imino-3-(2,4-diimino-5-thiazolidinylidene)-isoindoline as a yellow solid melting at 252°-263° C (dec.).
