Participants

Reaction Steps

The title compound was prepared in a manner analogous to Example 1, substituting (1R,6S)-8-(5-methylpyrazin-2-yl)-3,8-diazabicyclo[4.2.0]octane (Intermediate 29) 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 C20H20FN7O, 393.43; m/z found 394.1 [M+H]+. 1H NMR (CDCl3): 7.99-7.69 (m, 3H), 7.58-7.39 (m, 2H), 7.31 (s, 1H), 7.19-6.84 (m, 1H), 4.67-4.34 (m, 1H), 4.15-3.80 (m, 4H), 3.69-3.18 (m, 2H), 2.96 (br s, 1H), 2.45-2.05 (m, 5H).
