5-Hydroxy-2-hydroxymethyl-4-pyridone (1) and 5-hydroxy-2-hydroxymethyl-1-methyl-4-pyridone (2) reacted with arenediazonium salts to give 6-arylazo-substitued compounds 3a-d and 4a-d, respectively.Compounds 3a-d were methylated with diazomethane to afford 6-arylazo-2-hydroxymethyl-4,5-dimethoxypyridines 5a-d.
