Reaction Steps

2-Chloro-4-nitro-1H-imidazole (3 g, 20.34 mmol) and (S)-2-methyloxiran-2-ylmethyl 4-nitrobenzoate (5.31 g, 22.37 mmol) were dissolved in ethyl acetate (10 ml). Triethylamine (0.57 ml, 4.07 mmol) was added to the solution, and the resulting mixture was stirred at 60-65° C. for 10 hours. The reaction mixture was concentrated under reduced pressure. Ethyl acetate (3 ml) and toluene (30 ml) were added to the residue, and the resulting precipitates were filtered off to afford (S)-2-chloro-4-nitro-1-[2-hydroxy-3-(4-nitrobenzoyloxy)-2-methylpropyl]imidazole (6.82 g, yield 87%) as a yellow powder.
