Reaction Steps
To a mixture of 1-(4-fluorophenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-b]pyridine (0.023 g, 0.10 mmol), 4-chloro-3-(trifluoromethoxy)phenylacetic acid (0.025 g, 0.10 mmol) and Et3N (0.060 mL, 0.43 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 (0.039 g, 85%). 1H NMR (400 MHz, CDCl3) δ 8.47 (s, 1H), 7.44 (m, 3H), 7.12-7.22 (m, 4H), 3.90 (s, 2H), 3.76 (m, 2H), 2.80 (t, J=6.2 Hz, 2H), 2.02 (m, 2H); MS: (ES) m/z calculated for C21H16ClF4N3O2 [M+H]+ 454.1, found 454.1.
