Reaction Steps

6-Methoxy-2,3-naphthalenedicarboxylic anhydride (4.0 g) and pyridine hydrochloride (8.0 g) were fused at 240° for 0.5 hr. in a nitrogen atmosphere. The flask contents were cooled, washed (water) and filtered to give a crude sample of 6-hydroxy-2,3-naphthalenedicarboxylic anhydride (m.p. 266°) which was used without purification.
