Reaction Steps

6.24 g of 9-acridanone thiosemicarbazone, 3.5 g of sodium acetate and 5.2 ml of chloroacetaldehyde (50 percent aqueous solution) in 200 ml of methanol are heated to boiling under reflux for 6 hours. After evaporation of the solvent, the residue is treated with water. The precipitated product is filtered and washed successively with water, a small amount of ethanol, ether and petroleum ether. There is obtained 9-acridanone (2-thiazolyl)hydrazone of melting point 208°-210° (decomposition).
