A 100 mL pressure vessel was charged with 1-bromo-4-(phenylsulfonyl)benzene (1.00 g, 3.37 mmol, Example 17, step 1), 1,1,1,3,3,3-hexafluoro-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-2-propanol (1.62 g, 4.37 mmol), potassium carbonate (1.40 g, 10.10 mmol), tetrakis(triphenylphosphine)palladium (0) (0.194 g, 0.168 mmol), 20 mL of 1,2-dimethoxyethane, and 5 mL of water. The vessel was sealed and the reaction was heated to 100° C. for 2 h. After cooling to room temperature, the mixture was diluted with EtOAc (30 mL), separated, dried (MgSO4) and concentrated to give an oil. Purification via column chromatography (40 g of silica, 0 to 50% EtOAc in hexanes) produced a yellow solid that was slurried with cold (0° C.) MeOH (25 mL) to give 1,1,1,3,3,3-hexafluoro-2-(4′-(phenylsulfonyl)-4-biphenylyl)-2-propanol (0.650 g). 1H NMR (400 MHz, CD3OD) δ 8.08-7.95 (m, 4H), 7.91-7.74 (m, 6H), 7.69-7.54 (m, 3H). m/z (ESI, +ve ion) 461.0 (M+H)+. GK-GKRP EC50 (NADPH-coupled)=1.66 μM; GK-GKRP EC50 (LC MS/MS)=3.96 μM.
