Procedure

N,N-Dimethylformamide (0.5 ml) solution of (R)-1-(2-methyl-2-oxiranylmethyl)-4-nitro-2-(4-nitrophenylthio)imidazole (100 mg) and 3-(4-trifluoromethylphenyl)-2-propenyl piperazine-1-carboxylate (103 mg) was stirred at 60° C. for 1 day. Water and ethyl acetate were added to the reaction mixture, and 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: dichloromethane/methanol=50/1 to 30/1) and a basic silica gel column chromatography (eluent: dichlomethane), there was obtained 3-(4-trifluoromethylphenyl)-2-propenyl(S)-4-{3-[4-nitro-2-(4-nitrophenylthio)imidazol-1-yl]-2-hydroxy-2-methylpropyl]piperazin-1-carboxylate (173 mg, yield: 90%) as pale yellow amorphous product.
