4-methyl-1-(3-nitrothiophen-2-yl)-1H-imidazole was prepared from 2-chloro-3-nitrothiophene and 4-methyl-1H-imidazole according to the procedure described in Example 9.7.1., above. Purification by flash column chromatography (silica, 40:60 ethyl acetate/hexane) gave the nitro intermediate (1.26 g, 49%). 1H-NMR (CDCl3) δ 7.67 (s, 1H), 7.59 (d, J=6.1 Hz, 1H), 7.19 (d, J=6.1 Hz, 1H), 6.89 (s, 1H), 2.27 (s, 3H).
