Participants

Reaction Steps

Sodium bicarbonate (0.146 g) and N-bromosuccinimide (0.288 g) were added to a solution of 4-[3-(2-butynyl)-1-methyl-2-oxo-2,3-dihydro-1H-imidazo[4.5-c]pyridin-4-yl]-piperazine-1-carboxylic acid t-butyl ester (0.447 g) in N,N-dimethylformamide (20 mL). This was then stirred at room temperature for 60 hours. Sodium bicarbonate (0.219 g) and N-bromosuccinimide (0.432 g) were added again, and this was stirred at room temperature for 15 hours. Ethyl acetate (100 mL) and water (50 mL) were then added, and the organic layer was washed twice with 50 mL of water and then once with 50 mL of saturated aqueous sodium chloride solution, then was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography, and the hexane:ethyl acetate 1:1 fraction gave the title compound (0.201 g).
