A solution of 7.2 parts of 1,3-diiminoisoindoline in 100 parts of methanol was added to a solution of 7.2 parts of 2,4-dithioxo-thiazolidine in 75 parts of methanol under an atmosphere of nitrogen. The mixture was stirred at room temperature for 24 hours and the solid which separated was collected by filtration, washed with a small volume of fresh methanol and dried in vacuo at 50° C. to obtain 1-imino-3-(2,4-dithioxo-5-thiazolidinylidene)isoindoline as a red-orange crystalline solid which sintered at 268°-270° C.
