Versuchsvorschrift

A suspension of 4.68 g. of 9,10-anthracenedicarboxaldehyde in 200 ml. of ethanol containing 4.37 g. of 2-hydrazinopyridine and 2 drops of acetic acid is stirred and heated under reflux for two hours, then allowed to cool. Collection by filtration and washing with ethanol gives the desired product as an orange solid, which sinters from 267° C. to 272° C. (dec.).
