Reaction Steps

To a stirred solution of 0.1 g. (12 mmole) of imidazole in 20 ml. of N,N-dimethylformamide is added 0.5 g. (12 mmole) of 57.6 percent suspension of sodium hydride in mineral oil. After cooling to 20° C., 2.4 g. (10 mmole) of 3-bromo-2-nitrobenzofuran in 20 ml. of N,N-dimethylformamide is added. After stirring 45 minutes, the mixture is heated on a steam bath for 15 minutes, then 50 ml. of water are added. Cooling and filtration provide yellow needles of 3-(N-imidazolyl)-2-nitrobenzofuran, m.p. 147°-149° C.
