In the cation of the title compound, C(23)H(25)N(4)O(+)·PF(6) (-), the imidazolium ring make dihedral angles of 87.20 (6) and 79.89 (5)° with the pyridine ring and the quinoline system, respectively. In the crystal, C-H⋯F and C-H⋯N hydrogen bonds are observed.

In the cation of the title salt, C(19)H(19)N(4)O(2) (+)·Cl(-), the dihedral angles between the imidazole ring and the phenyl rings are 70.39 (8) and 86.26 (9)°. The chloride anion inter-acts with the cation through an N-H⋯Cl hydrogen bond. In the crystal, classical N-H⋯O hydrogen bonds link the cations into chains parallel to the b axis. Non-classical C-H⋯Cl and C-H⋯O hydrogen bonds further con...

A promising imidazole compound was synthesized through the following route. The reaction of 5-methyl-2-phenyl-1H-imidazole-4-carbohydrazide (1) with carbon disulfide and potassium hydroxide in ethanol (80%) afforded salt (2). Refluxing (2) phenacyl bromide (3) ethanol/water (1:1) gave 2-((5-(5-methyl-2-phenyl-1H-imidazol-4-yl)-1,3,4-oxadiazol-2-yl)thio)-1-phenylethan-1-one (4) a 76% yield. stru...

6-Methyl-2-phenyl-7H-Oxazolo [3,2-b] [1,2,4] triazine (1) undersent ting transformation on treatment with ammonia and primary amines to afford the corresponding imidazol [1,2-b][1,2,4] triazine (2). Treatment of (1) with hydrazine hydrate gave the corresponding 3-aryl-4H-1,2,4- triazino [4,3-b][1,2,4] triazin-8 (1H)-one (3).
