Reaction Steps

The title compound was prepared from 2-(5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)butanoic acid and 1-(4-fluorophenyl)-5-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-b]pyridine using General Method A. The reaction slurry was purified by reverse phase HPLC (C18 column, acetonitrile-H2O with 0.1% TFA as eluent) to provide 13 mg (46%) of the title compound as a white solid. 1H NMR (400 MHz, CDCl3) δ 8.40 (s, 1H), 7.47 (m, 2H), 7.16 (m, 2H), 6.35 (s, 1H), 5.37 (dd, J=6.7, 8.6 Hz, 1H), 4.63 (m, 1H), 2.86 (m, 1H), 2.73 (ddd, J=1.9, 5.1, 11.3 Hz, 1H), 2.37 (s, 3H), 2.27 (m, 2H), 1.92-1.97 (m, 2H), 0.93 (t, J=6.5 Hz, 3H), 0.57 (t, J=6.7 Hz, 3H); MS: (ES) m/z calculated for C22H24F4N5O [M+H]+ 450.2, found 450.2.
