Procedure

To a mixture of 1-(4-fluorophenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-b]pyridine (0.023 g, 0.10 mmol), 2-(4-chloro-3-difluoromethyl-5-methyl-pyrazol-1-yl)acetic acid (0.023 g, 0.10 mmol) and NEt3 (0.065 mL, 0.46 mmol) in DMF (0.6 mL) was added HATU (0.060 g, 0.15 mmol). The mixture was stirred at rt for 30 min. It was then quenched with water and partitioned between EtOAc (50 mL) and sat. NaHCO3 (30 mL). The organic layer was separated, dried over Na2SO4, concentrated in vacuo and purified by reverse phase HPLC to afford the desired product (0.032 g, 75%). 1H NMR (400 MHz, CDCl3) δ 8.36 (s, 1H), 7.44 (m, 2H), 7.16 (dd, J=8.8, 8.4 Hz, 2H), 6.67 (d, J=54 Hz, 1H), 5.11 (s, 2H), 3.83 (m, 2H), 2.85 (t, J=6.2 Hz, 2H), 2.30 (s, 3H), 2.10 (m, 2H); MS: (ES) m/z calculated for C19H17ClF3N5O [M+H]+ 424.1, found 424.1.
