Reaction Conditions

Reaction Steps

To 5-bromo-2-(methylthio)pyridine (14.0 mg, 0.07 mmol), were added 1,2-dimethoxyethane (1.5 mL) and Pd(PPh3)4 (8.4 mg, cat.). To the reaction mixture, were added 1-(2-chloro-phenyl)-5-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-3-[di-(trifluoromethyl)-hydroxy-methyl]-4,5-dihydro-1H-pyrazole (25.0 mg, 0.05 mmol) prepared in Step 1, ethanol 183.0 uL, and a 2N sodium carbonate solution (183.0 uL). The reaction mixture was stirred at 88° C. for 2 hours and then distilled water was added thereto. The reaction mixture was extracted with diethyl ether two 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=1/5) to give 8.0 mg of the titled compound as a white liquid.
