A suspension of 4.68 g. of anthracene-9,10-dicarboxaldehyde in 100 ml. of ethanol containing 4.13 g. of [2-(dimethylamino)ethyl]hydrazine [Elslager et al., J. Med. Chem. I, 493 (1964)] containing two drops of acetic acid is stirred and heated under reflux for two hours. The resulting solution is filtered, concentrated, allowed to cool to 45° C., diluted with petroleum ether, then allowed to cool further at 5° C. The desired product separates as an orange solid and is collected by filtration.
