Reaction Steps

To this, 0.3 ml of 1.62 M hexane solution of n-butyllithium was added under a stream of nitrogen, and the mixture was stirred for 10 minutes. The mixture was cooled to -78° C., and 85 mg (0.31 mmol) of [1,2-dimethyl-5-(3,5-dimethylphenylthio)imidazol-4-yl]acetonitrile (42d) was added, and the mixture was stirred for 15 minutes. Then, 86 mg (0.48 mmol) of hexamethylphosphoric triamide and 68 mg (0.48 mmol) of methyl iodide were added dropwise, and the mixture was stirred at -78° C. for 30 minutes. The reaction mixture was poured into ice-water, extracted with diethyl ether, and the extract was washed with water and dried over sodium sulfate. The solvent was distilled off under reduced pressure, the residue was purified by silica gel chromatography (ethyl acetate) to give 51 mg of 2-[1,2-dimethyl-5-(3,5-dimethylphenylthio)-1H-imidazol-4-yl]propiononitrile (43a) as oil (yield 57%).
