Procedure

N,N-Dimethylformamide (0.25 ml) solution of (R)-1-(2-methyl-2-oxiranylmethyl)-4-nitro-2-(2-nitrophenylthio)imidazole (50 mg) and 3-(4-trifluoromethylphenyl)-2-propenyl piperazin-1-carboxylate (51 mg) was stirred at 60° C. for 1 day. 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, 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 thin layer chromatography (eluent: dichloromethane/methanol=30/1), there was obtained 3-(4-trifluoromethylphenyl)-2-propenyl(S)-4-{3-[4-nitro-2-(2-nitrophenylthio)imidazol-1-yl]-2-hydroxy-2-methylpropyl}piperazin-1-carboxylate (86 mg, yield: 87%) as yellow amorphous product.
