Abstract 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‐substituted 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 .
