실험 절차

To a solution of 2-[2-(4-chloro-phenyl)-2,4,5,6-tetrahydro-cyclopentapyrazol-3-yl]-2-cyclohexyl-ethanol (250 mg, 0.72 mmol; example 1.4) in dry dichloromethane (5 ml) was added triethylamine (0.32 ml, 1.19 mmol) at 25° C. Mesyl chloride (0.16 ml, 0.725 mmol) was added dropwise at 0° C. The reaction mixture was allowed to stir at 25° C. for 2 h, diluted with water (5 ml), and the aqueous layer was extracted with dichloromethane (3×10 ml). The combined organic layers were washed sequentially with ice water (10 ml), 10% aqueous NaHCO3 solution (10 ml), brine (10 ml) and finally dried over Na2SO4. The solvent was removed under reduced pressure to give the title compound as light yellow oil (250 mg, 0.58 mmol; 81%), which was sufficiently pure to be used in the next reaction step.
