Reaction Steps
A mixture of (S)-cyclopropyl(5-(6-fluoropyridin-2-yloxy)-2-methyl-6-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-3,4-dihydroquinolin-1(2H)-yl)methanone (0.024 g, 0.05 mmol), and sodium methoxide (0.015 g, 0.28 mmol) in N,N-dimethylformamide (1 mL) stirred overnight at 80° C. The reaction mixture was cooled to room temperature, diluted with ethyl acetate (15 mL), washed with brine (2×5 mL), dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. The residue was purified by preparative-HPLC with the following conditions (Waters I): Column, SunFire Prep C18, 5 um, 19×100 mm; mobile phase, water (0.05% ammonium bicarbonate) and acetonitrile (16% to 34% acetonitrile in 10 min, flow rate: 20 mL/min); Detector, UV 220&254 nm. This afforded (S)-cyclopropyl(5-(6-methoxypyridin-2-yloxy)-2-methyl-6-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-3,4-dihydroquinolin-1(2H)-yl)methanone (0.0033 g, 13%) as a white solid. 1H NMR (400 MHz, CD3OD) δ ppm 0.79-0.87 (m, 1H), 0.91-1.00 (m, 2H), 1.10-1.18 (m, 4H), 1.39-1.49 (m, 1H), 1.79-1.84 (m, 2H), 1.97-2.09 (m, 3H), 2.18-2.41 (m, 2H), 2.62-2.79 (m, 3H), 3.12-3.19 (m, 2H), 3.62 (s, 3H), 4.15-4.27 (m, 1H), 4.72-4.89 (m, 1H), 6.41 (t, J=8.00 Hz, 2H), 7.36 (d, J=8.40 Hz, 1H), 7.55-7.65 (m, 2H), 7.79 (s, 1H), 7.96 (s, 1H). MS (ESI, pos. ion) m/z 488 [M+H]+.
