Reaction Steps

5-(3-Bromo-phenyl)-1-(2-chloro-phenyl)-3-pentafluoroethyl-4,5-dihydro-1H-pyrazole (20.0 mg, 0.04 mmol) prepared in Step 1 of Preparation 6, 3-(trifluoromethyl)phenylboronic acid (17.0 mg, 0.09 mmol), Pd(PPh3)4 (2.5 mg, cat.) and a 2N sodium carbonate solution (1.0 mL) were added to N,N-dimethylformamide (2.0 mL). The reaction mixture was stirred at 80° C. for 2 hours and then filtered through celite pad. A saturated solution of ammonium chloride was added to filtrate, which was then extracted with ethyl acetate three times. The combined extract was washed with 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=1/8) to give 18.0 mg of the titled compound as a yellow liquid.
