Dimethylcarbamoyl Chloride → 3-(2-Methylimidazo[1,2-a]pyridin-3-yl)sulfonyl-1-dimethylcarbamoyl-1H-1,2,4-triazole

Participants

Reaction Steps

To a mixture of 3-(2-methylimidazo[1,2-a]pyridin-3-yl)sulfonyl-1H-1,2,4-triazole (100 mg), anhydrous potassium carbonate (105 mg) and N,N-dimethylformamide (0.5 ml) was added dimethylcarbamoyl chloride (0.06 ml), and the reaction mixture was stirred at room temperature overnight. The reaction solution was extracted with ethyl acetate-water. The organic layer was washed with water, followed by saturated aqueous sodium chloride solution, and concentrated. The residue was subjected to a silica-gel column chromatography with 30 to 50% (20% 2-propanol/ethyl acetate)/hexane to yield the title compound (107 mg).
