Procedure

A mixture of 4-(1-(2-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenol (169 mg, 0.5 mmol), 3-methylsulfonylphenylboronic acid (200 mg, 1 mmol), Cu(OAc)2 (181 mg, 1 mmol), and NEt3 (35 μL, 2.5 mmol) and molecule sieves (4A) in DCM was shaken overnight at 20° C. Solid was removed by filtration and filtrate was evaporated to give a crude, which was purified by column chromatography on silica gel eluting with EtOAc-hexane (1:4 to 1:2) to afford 1-(2-chlorophenyl)-5-(4-{[3-(methylsulfonyl)phenyl]oxy}phenyl)-3-(trifluoromethyl)-1H-pyrazole (88 mg). 1H-NMR: CDCl3: 7.68 (m, 1H), 7.55 (m, 2H), 7.48 (m, 1H), 7.62-7.40 (m, 2H), 7.27 (m, 2H), 7.21 (m, 1H), 6.93 (m, 1H), 6.80 (s, 1H), 3.04 (s, 3H), MS(ES): 493 [M+H]+.
