Diethoxymethyl acetate was used to cyclize o ‐disubstituted aminopyridines to oxazolo[4,5‐ c ]pyridines and imidazo[4,5‐ c ]pyridines. All the possible imidazole‐methylated imidazo[4,5‐ c ]pyridines were prepared. A novel synthesis of 2‐substituted thiazolo[5,4‐ c ]pyridines and 4‐amino‐3‐pyridinethiol was discovered.
