Example 303 was prepared in a manner analogous to Intermediate 59 substituting the product of Step C for Intermediate 15 and Intermediate 12 for 2-(4H-[1,2,4]triazol-3-yl)-benzoic acid. MS (ESI) mass calculated for C19H19FN8O, 394.41; m/z found, 395.0. 1H NMR (500 MHz, CDCl3): 8.51-8.42 (m, 1H), 7.89-7.81 (m, 2H), 7.75 (d, J=3.5 Hz, 1H), 7.54-7.45 (m, 1H), 7.20-7.11 (m, 1H), 4.02-3.51 (m, 8H), 3.32-3.23 (m, 1H), 3.17-3.00 (m, 2H), 2.50-2.40 (m, 3H).
