Reaction Steps
(R)-2-Chloro-1-(2-methyloxiran-2-ylmethyl)-4-nitroimidazole prepared in Example 12 (0.500 g, 2.29 mmol) and 4-piperidinopiperidine (0.425 g, 2.53 mmol) were dissolved in DMF (5 ml), and the solution was stirred at 70° C. for 5 hours. The reaction mixture was added water and extracted with ethyl acetate twice. The organic phases were combined, washed with water and a saturated saline solution, dried over sodium sulfate and then filtered. The resulting filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/ethyl acetate=3/2) using basic silica gel to afford (S)-1-(4-piperidinopiperidin-1-yl)-3-(2-chloro-4-nitroimidazol-1-yl)-2-methyl-propan-2-ol (0.656 g, yield 74%) as a brown oil.
