Procedure

1-(2-Chloro-phenyl)-5-[6-(1,2,3,6-tetrahydropyridin-4-yl)-pyridin-3-yl]-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole hydrochloride (30.0 mg, 0.06 mmol) prepared in Example 356, methanesulfonyl chloride (6.0 uL, 0.08 mmol), and triethylamine (38.0 uL, 0.28 mmol) were added to dichloromethane (1.0 mL). The reaction mixture was stirred at room temperature for 16 hours, washed with distilled water and brine, dried on anhydrous magnesium sulfate, and then concentrated under reduced pressure to give a yellow liquid residue. The resulting residue was purified by silica gel column chromatography (eluent: ethyl acetate/n-hexane=2/1) to give 5.0 mg of the titled compound as a yellow liquid.
