Reaction Steps

6.15 g (12.4 mmol) of the 2-benzyloxy-1-((4-methoxybenzylthio)(methylimino)methyl)-1-(4-nitroimidazol-1-yl)cyclohexane prepared in the Preparative Example 14 was dissolved in 25 ml of trifluoroacetic acid under cooling with ice, followed by the addition of 5 ml of anisole. The obtained mixture was stirred at 0° C. for 10 minutes to give a dark-brown solution, which was pored onto a mixture comprising a saturated aqueous solution of sodium hydrogencarbonate and ice. The obtained mixture was extracted with ethyl acetate. The organic phase was washed with a saturated aqueous solution of common salt, dried over anhydrous sodium sulfate, and concentrated in a vacuum. The residue (8.02 g) was purified by silica gel column chromatography [solvent: dichloromethane/acetone (40:1)], and recrystallized from dichloromethane/diisopropyl ether to give 3.14 g of the title compound as a colorless crystal (yield: 67%).
