Reaction Steps

1-(3-Bromo-phenyl)-5-(2-chloro-phenyl)-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole (50.0 mg, 0.10 mmol) prepared in Step 2 of Preparation 25, 3-methylthiophenylboronic acid (20.0 mg, 0.15 mmol), Pd(PPh3)4 (11.5 mg, 0.01 mmol), and a 2N sodium carbonate solution (0.5 mL) were added to a mixed solvent of 1,2-dimethoxyethane (2.0 mL) and ethanol (0.5 mL). The reaction mixture was stirred at 90° C. for 2 hours and then ethyl acetate was added thereto. The reaction mixture was 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=1/10) to give 5.3 mg of the titled compound as a yellow liquid.
