70% In water; at 80℃; for 3h; General procedure: To a stirred solution of aryl thioamide or amidine (1 mmol) in 5 mL distilled water was added alpha-tosyloxyketone (1 mmol) and the reaction mixture stirred at 60 C or 80 C till completion. Progress of the reaction was monitored by thin layer chromatography. After completion of the reaction, product was readily filtered and recrystallized from ethanol (3a-k, 3p-o and 4a-e). In some cases (3l-m and 4f-i) product was extracted with dichloromethane (25 mL), washed with brine (25 mL), the organic layers were combined, dried over anhydrous Na2SO4 and distilled off in vacuum. The residue so obtained was purified by column chromatography on silica gel (100-200 mesh) (EtOAc/Hexane) to give pure product.

In chloroform; water; SYNTHESIS EXAMPLE 1 [SYNTHESIS OF COMPOUND EXAMPLE (2)] Synthesis of 2,4-diphenylimidazole A dissolution of 7 g of a benzamidine chloride was made in 30 ml of water. The resulted solution was further added with a solution of 5 g of caustic potash dissolved in 15 ml of water, so that benzamidine was deposited. The resulted matter was added with 20 ml of chloroform and the whole amount of the solution was poured into a separating funnel and was then shaked well so as to separate a chloroform layer. The resulted chloroform solution was added with 3.0 g of bromoacetophenone while stirring and, next, the resulted solution was boiled and refluxed for 3 hours. When the chloroform was vacuum-distilled off therefrom, an oily matter remained. When the oily matter was washed well several times in warm water, it was crystallized. Next, when it was recrystallized with 10 ml of alcohol, 2.0 g of a white powder were obtained. Melting point: 168 to 175 C.
