Reaction Conditions

Reaction Steps

In 50 ml of pyridine was dissolved 5.0 g (28.4 millimoles) of 2-mercapto-4-phenylimidazole, and 3.13 ml (34.1 millimoles) of N,N-dimethylcarbamoyl chloride was added to the solution and the mixture was heated at 70° C. for 3 hours. The reaction mixture was concentrated under reduced pressure, and 200 ml of water and 200 ml of chloroform were added to the concentrate to effect extraction. The chloroform layer was concentrated and the concentrate was recrystallized from ethanol to obtain 2.4 g (yield=34%) of intended 2-(N,N-dimethylcarbamoylthio)-4-phenylimidazole (compound No. 21) in the form of a colorless crystal.
