Participants

Reaction Steps

The title compound was prepared from 2-(3-(trifluoromethyl)-1H-1,2,4-triazol-1-yl)acetic acid and 1-(4-fluorophenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-b]pyridine using General Method B. The product mixture was washed with 2× brine. The reaction slurry was purified by reverse phase HPLC (C18 column, acetonitrile-H2O with 0.1% TFA as eluent) to provide 33 mg of the title compound as a white solid. 1H NMR (400 MHz, CD3OD, mixture of rotamers) δ 8.41 (s, 1H), 8.35 (s, 0.75H), 7.60 (s, 0.25H), 7.43-7.50 (m, 2H), 7.15-7.23 (m, 2H), 5.41 (s, 0.5H), 5.30 (s, 1.5H), 3.94 (m, 0.5H), 3.84 (m, 1.5H), 2.89 (m, 2H), 2.15 (m, 1.5H), 2.07 (m, 0.5H); MS: (ES) m/z calculated for C17H15F4N6O [M+H]+ 395.1, found 395.1.
