Reaction Steps

A mixture of 4,4'-di(trifluoromethyl)benzoin (50 g, 0.15 mol) and thiourea (15.2 g, 0.2 mol) in dimethylformamide (350 ml) was refluxed under argon for three hours. The cooled solution was poured into 1 liter of water and the resulting solid was collected, washed with water, air-dried and recrystallized from ethanol to give 4,5-bis-(4-trifluoromethylphenyl)-1H-imidazole-2-thione, m.p. 312°-315°.
