To a solution of 100 mg (0.35 mmol) of 4-(2-Methyl-4-m-tolylethynyl-imidazol-1-yl)-1H-pyridin-2-one in 0.5 ml of dimethylformamide were added 17 mg (0.42 mmol, 1.2 equiv.) of a 60% sodium hydride suspension in mineral oil. After stirring for 1 h at room temperature, 40 uL (50 mg, 0.52 mmol, 1.5 equiv.) of chloromethyl methylsulfide were added and the suspension was stirred for another 16 h at room temperature. After workup with methylene chloride/water, the crude material was purified by flash chromatography (SiO2, gradient ethyl acetate to ethyl acetate:methanol 90:10 v/v) to yield 32 mg of the title compound as a light yellow solid, MS: 350.2 (M+H+).
