Procedure

N,N-Diisopropylethylamine (3.64 mL) was added to a solution of [2-(3-nitrophenyl)cyclohex-1-enyl]methanol obtained in Preparation Example 4-(2) (1.67 g) in dichloromethane (109 mL) in an ice bath. Then, methanesulfonyl chloride (668 μL) was added dropwise. The reaction mixture was warmed to room temperature and stirred overnight. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The drying agent was removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (1.56 g).
