Reactions of 4‐amino‐1,2‐dimethylimidazole‐5‐carbaldehyde ( 1 ) and 5‐amino‐1‐methylimidazole‐4‐car‐baldehydes 3 with nitriles, in the presence of dry hydrogen chloride afforded to the formation of purine derivatives. This constitutes a facile and versatile one‐pot synthesis of purines. The use of formamide instead of nitriles leads to the respective purines without substituents on the pyrimidine ring, 2d and 4e,f .
