Procedure
(R)-2-Chloro-1-(2-methyloxiran-2-ylmethyl)-4-nitroimidazole prepared in Example 12 (500 mg, 2.30 mmol) and 4-(4-trifluoromethylphenoxy)piperidine (730 mg, 3.0 mmol) in DMF (10 ml) were stirred at 70-75° C. for 5 hours. The reaction mixture was allowed to return to room temperature, poured into water, and extracted with ethyl acetate. The extract was washed with a saturated saline solution, dried over magnesium sulfate and then filtered. The filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (methylene chloride/methanol=50/1) to afford (S)-1-(2-chloro-4-nitroimidazol-1-yl)-2-methyl-3-[4-(4-trifluoromethylphenoxy)piperidin-1-yl]propan-2-ol (1.06 g, yield 99%) as a yellow oil.
