Procedure
4-Carbethoxy-5-amino-2-(3-pyridyl)imidazole hydrochloride (1.90 gm) was dissolved in 5N hydrochloric acid (10 mls) and the mixture stirred at room temperature. A solution of sodium nitrite (0.5 gm) in water (5 ml) was then added in small portions, and the resulting clear solution stirred for 5 minutes. The mixture was then poured into a vigorously stirred mixture of 30% aqueous dimethylamine (1.0 ml) and 10% aqueous sodium carbonate (20 mls) giving a pale brown precipitate. The crude product was recrystallized from methanol/ether to give 0.65 gm of an off-white solid mp. 125° with decomposition.
