Procedure
4.0 g of m-methylthiobenzonitrile, 2.7 g of dicyanodiamide and 2.0 g of caustic potash are dissolved in 20 ml of methyl cellosolve, and the mixture is refluxed for 4 hours. After cooling, the mixture is diluted with water and the separated crystals are recrystallized from dioxane. Melting point: 229°-230° C.; Yield: 3.4 g.
