Reaction Steps
Cyanogen bromide (6.0 g, 0.057 mol) was added to a stirred solution of 1-[4-(diethylamino)-2-butynyl]-1,3-dihydro-3-methyl-2H-imidazol-2-one in dioxane (130 mL). After evaporation of the dioxane, the residual oil was chromatographed on silica gel using chloroform:1% methanol as the eluant to give 10.8 g of 1-(4-bromo-2-butynyl)-1,3-dihydro-3-methyl-2H-imidazol-2-one as an oil.
