実験手順

(R)-2-Chloro-1-(2-methyloxiran-2-ylmethyl)-4-nitroimidazole prepared in Example 12 (700 mg, 3.22 mmol) and 4-(4-trifluoromethylbenzyloxy)piperidine (1.09 g, 4.86 mol) in DMF (10 ml) were stirred at 70-75° C. for 4 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-trifluoromethylbenzyloxy)piperidin-1-yl]propan-2-ol (1.36 g, yield 87%) as a yellow oil.
