To a solution of 2-chloro-1-[2-hydroxy-2-methyl-3-(4-methylbenzenesulfonyloxy)propyl]-4-nitroimidazole prepared in Example 5 (0.30 g, 0.77 mmol) and 4-(4-trifluoromethylphenoxy)piperidine (0.21 g, 0.85 mmol) in DMF (6 ml), sodium iodide (0.13 g, 0.77 mmol) and triethylamine (0.12 ml, 0.77 mmol) were added followed by stirring at 80° C. for 7 hours. To the reaction mixture, water was added, and the resulting solution was extracted with ethyl acetate. The organic phase was washed with water, dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (methylene chloride/ethyl acetate=9/1) to afford 1-(2-chloro-4-nitroimidazol-1-yl)-2-methyl-3-[4-(4-trifluoromethylphenoxy)piperidin-1-yl]propan-2-ol (0.23 g, yield 63%) as a yellow oil.
