실험 절차

A mixture of 2.34 g. of 9,10-anthracenedicarboxaldehyde and 3.65 g. of thiosemicarbazide in 250 ml. of absolute ethanol containing 2.0 ml. of glacial acetic acid is heated on a steam bath for 24 hours, allowed to cool and then let stand overnight. The solid is collected, washed with absolute ethanol, dried and recrystallized from aqueous dimethylformamide giving the desired product as orange crystals, m.p. 275°-277° C.
