Synthesis of 1-aminoanthrapyridones and their derivatives
Abstract1-Aminoanthrapyridones are obtained when 1-anthrapyridonylpyridinium chlorides are heated in high-boiling amines. The synthesis of a number of substituted N-chloroacetyl-1-aminoanthraquinones. 1-anthrapyridonylpyridinium chlorides. and 1-aminoanthrapyridones is described.
