Reaction Steps

The title compound was prepared as described in Example 10 using 3-(4-bromophenyl)-1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazole (C52) with tetrakis(triphenylphosphine)palladium(0) as catalyst, sodium carbonate as base and heating to 100° C. for 3 hours; isolated as an orange solid (2.18 g, 57%, 79% pure): 1H NMR (400 MHz, CDCl3) δ 8.56 (s, 1H), 8.15-8.06 (m, 2H), 7.80 (dd, J=9.0, 2.3 Hz, 2H), 7.50 (d, J=8.4 Hz, 2H), 7.39 (ddd, J=8.0, 2.5, 1.3 Hz, 2H), 6.28-6.21 (m, 1H), 2.46 (ddt, J=6.3, 4.1, 2.0 Hz, 2H), 2.24 (dtd, J=6.3, 3.8, 1.8 Hz, 2H), 1.85-1.75 (m, 2H), 1.71-1.63 (m, 2H); 19F NMR (376 MHz, DMSO-d6) δ −58.03; ESIMS m/z 386 ([M+H]+).
