6-Bromo-N-methylpyridone reacts with phosphorus pentachloride at 180° C to form, 2, 6-dichloroanthrapyridine. The latter reacts with amines at moderate temperatures forming 6-amino-2-chloro derivatives of anthrapyridine and at high temperatures form

It is shown that hydrogen chloride catalyzes the replacement of halogen in the reaction of halogenoanthrapyridines with aromatic amines. Cupric acetate, in the presence of potassium acetate at 80–120° C, does not catalyze the replacement of haloge
