Procedure
The title compound was prepared from a Suzuki coupling of 4-Methyl-2-(5-trifluoromethanesulfonyloxy-4′-trifluoromethyl-biphenyl-3-yl)-pentanoic acid ethyl ester (intermediate Example 1g) with 2-fluoro-phenylboronic acid under the conditions described in Example 1; 1H NMR (400 MHz, CHLOROFORM-D) δ ppm 0.94 (td, J=19.93, 6.60 Hz, 6H), 1.58 (dt, J=13.39, 6.63 Hz, 1H), 1.78 (ddd, J=13.69, 7.21, 6.97 Hz, 1H), 2.01-2.11 (m, 1H), 3.80 (t, J=7.83 Hz, 1H), 7.16-7.27 (m, 2H), 7.29-7.40 (m, 1H), 7.47 (td, J=7.70, 1.71 Hz, 1H), 7.52-7.61 (m, 2H), 7.66-7.76 (m, 5H); Calcd for C25H22F4O2 (M+Na) 453.16, Found 453.
