Reaction Steps

The title compound was prepared in a manner analogous to Example 1, substituting (1R,6S)-8-(3,6-Dimethyl-pyrazin-2-yl)-3,8-diaza-bicyclo[4.2.0]octane (Intermediate 10) for (1R,6S)8-(4,6-dimethyl-pyrimidin-2-yl)-3,8-diaza-bicyclo[4.2.0]octane and 2-Fluoro-6-[1,2,3]triazol-2-yl-benzoic acid (Intermediate 15) for 2-thiophen-2-yl-benzoic acid. DCM was used in place of DMF. MS (ESI) mass calcd. For C21H22FN7O, 407.45; m/z found 408.2 [M+H]+. 1H NMR (CD3OD): 7.96-7.23 (m, 6H), 4.50-4.44 (m, 1H), 4.31-4.19 (m, 2H), 4.11-3.77 (m, 3H), 3.62-3.42 (m, 1H), 2.86-2.77 (m, 1H), 2.40-2.36 (m, 3H), 2.31-2.05 (m, 2H), 2.04-1.92 (m, 3H).
