Reaction Steps

To N,N-dimethylformamide (5 ml) solution of 2-(4-nitrophenylthio)imidazole (500 mg) was added sodium hydride (90 mg) at 0° C., then reaction mixture was stirred at a room temperature for 30 minutes. After being cooled again the reaction mixture to 0° C., 2-methyl-2-oxiranylmethyl(S)-4-nitrobenzenesulfonate (618 mg) was added and stirred at a room temperature for 3.5 hours. Water and ethyl acetate were added to the reaction mixture, the organic layer was taken by separation. The ethyl acetate layer was washed with water and an aqueous solution being saturated with sodium chloride, then dried over anhydrous sodium sulfate. The residue obtained by removal of the solvent by distillation was purified by use of a silica gel column chromatography (eluent: dichlormethane/ethyl acetate=17/3), there was obtained (R)-1-(2-methyl-2-oxiranylmethyl)-2-(4-nitrophenylthio)imidazole (604 mg, yield: 91%) as yellow oily product.
