Reaction Steps

The title compound was prepared in a manner analogous to Example 1, substituting (1R,6S)-[8-(6-methyl-2-trifluoromethyl-pyrimidin-4-yl)-3,8-diaza-bicyclo[4.2.0]octane (Intermediate 9) for (1R,6S)8-(4,6-dimethyl-pyrimidin-2-yl)-3,8-diaza-bicyclo[4.2.0]octane and 3-fluoro-6-[1,2,3]triazol-2-yl-benzoic acid (Intermediate 15) for 2-thiophen-2-yl-benzoic acid. Additionally, the reaction time was shortened to 30 minutes. MS (ESI) mass calcd. for C21H19F4N7O, 461.42; m/z found 462.1 [M+H]+. 1H NMR (400 MHz, CDCl3): 7.89-7.60 (m, 3H), 7.57-7.27 (m, 1H), 7.20-6.99 (m, 1H), 6.90-6.55 (m, 1H), 4.85 (5, br, 0.35H), 4.50-3.12 (m, 7H), 2.97-2.57 (m, 1.65H), 2.44-2.04 (m, 7H).
