Reaction Steps
A mixture of 3-(trifluoromethyl)-1,4,6,7-tetrahydropyrano[4,3-c]pyrazole (0.050 g, 0.26 mmol), 2-chloro-1-[1-(4-fluorophenyl)-6,7-dihydro-5H-pyrazolo[4,3-b]pyridine-4-yl]ethanone (0.050 g, 0.17 mmol) and K2CO3 (0.130 g, 0.94 mmol) in THF (0.8 mL) and DMF (0.4 mL) was heated at 55° C. for 1 hr. It was then cooled to rt. The mixture was 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 (0.035 g, 55%). 1H NMR (400 MHz, CDCl3) δ 8.38 (s, 1H), 7.44 (dd, J=8.8, 4.6 Hz, 2H), 7.17 (dd, J=8.8, 8.0 Hz, 2H), 5.13 (s, 2H), 4.75 (s, 2H), 3.98 (t, J=5.4 Hz, 2H), 3.87 (m, 2H), 2.85 (t, J=6.2 Hz, 2H), 2.79 (t, J=5.6 Hz, 2H), 2.10 (m, 2H); MS: (ES) m/z calculated for C21H19F4N5O2 [M+H]+ 450.1, found 450.1.
