실험 절차

A mixture of 1-[1-(4-fluorophenyl)-6,7-dihydro-5H-pyrazolo[4,3-b]pyridin-4-yl]-2-[5-methyl-3-(trifluoromethyl)pyrazol-1-yl]ethanone (0.100 g, 0.25 mmol), 4-(iodomethyl)tetrahydro-2H-pyran (0.165 g, 0.75 mmol) and NaH (0.030 g, 0.75 mmol, 60% in mineral oil) in DMF (0.8 mL) was stirred at rt for 1.5 hrs. It was then quenched with sat. NH4Cl. The mixture was partitioned between EtOAc (50 mL) and brine (30 mL). The organic layer was separated, dried over Na2SO4, concentrated in vacuo, and purified by reverse phase HPLC to afford the desired product (0.007 g, 6%). 1H NMR (400 MHz, CDCl3) δ 8.44 (s, 1H), 7.43 (dd, J=8.8, 4.8 Hz, 2H), 7.16 (dd, J=8.8, 8.4 Hz, 2H), 6.31 (s, 1H), 5.54 (m, 1H), 3.95 (m, 2H), 3.78 (m, 1H), 3.47 (m, 1H), 3.34 (m, 2H), 2.75 (m, 2H), 2.30 (s, 3H), 2.20 (m, 3H), 1.88 (m, 3H), 1.40 (m, 3H); MS: (ES) m/z calculated for C25H27F4N5O2 [M+H]+ 506.2, found 506.2.
