5.0 g of 9-chloro-1-nitroacridine, 3.8 g of 2-hydrazino-2-thiazoline hydrobromide and 3.17 g of anhydrous sodium acetate are dissolved in 250 ml of dry methanol, heated on a steam-bath for 1 hour and then left to stand overnight. The precipitated material is filtered and recrystallized from methanol. There is obtained 1-nitro-9-acridanone (2-thiazolidinylidene)hydrazone which beings to decompose from 152°.
