Participants

Reaction Steps

To a solution of 0.25 g (1.0 millimole) of 2-(N,N-dimethylcarbamoylthio)-4-phenylimidazole in 10 ml of N, N-dimethylformamide was added 0.04 g (1.0 millimole) of sodium hydride, and the mixture was stirred at room temperature for 1 hour. Then, 0.16 g (1.0 millimole) of 2-chloro-5-nitropyridine was added to the mixture, and the mixture was stirred at room temperature for 3 hours. The mixture was concentrated under reduced pressure and washed with water and ethyl acetate to obtain 0.27 g (yield=73%) of intended 2-(N,N-dimethylcarbamoylthio)-1-(5-nitropyridinyl)-4-phenylimidazole (compound No. 28) in the form of a yellow powder.
