Procedure

5-(2-Chloro-phenyl)-1-[3-(4-BOC-piperazin-1-yl)-phenyl]-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole (100.0 mg, 0.20 mmol) prepared in Example 436 was added to a saturated solution of hydrochloric acid in ethyl acetate (3.0 mL). The reaction mixture was stirred at room temperature for 1 hour and then concentrated under reduced pressure to give 400.0 mg of 5-(2-chloro-phenyl)-1-[3-(piperazin-1-yl)-phenyl]-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole hydrochloride as a yellow liquid.
