Abstract
Two new types of imidazole derivatives: N‐(2‐R1‐5‐R2‐1H‐imidazol‐4‐yl) thioureas 7a–g and N‐(2‐R1‐5‐R2‐1H‐imidazol‐4‐yl) formamides 8b,c,g were obtained in high yields by the hydrolytic degradation of 6‐R1‐8‐R2‐2‐thioxo‐2,3‐dihydroimidazo[1,5‐a]‐1,3,5‐triazin‐4(1H)‐ones 5a–g and 6‐R1‐8‐R2‐imidazo[1,5‐a]‐1,3,5‐triazin‐4(3H)‐ones 6b,c,d, respectively. The tautomeric preferences of the new imidazoles were determined.
