Procedure

The 5-(2-chloro-phenyl)-1-[3-(piperazin-1-yl)-phenyl]-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole hydrochloride (30.0 mg, 0.055 mmol) in the form of a yellow liquid, cyclopropanesulfonyl chloride (9.3 mg, 0.066 mmol), and triethylamine (31.0 uL, 0.221 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=1/2) to give 15.0 mg of the titled compound as a yellow liquid.
