実験手順

Trifluoroacetic acid (0.5 mL, 6.49 mmol) was added to a solution of (S)-tert-butyl 4-(4-(1-acetyl-2-methyl-5-propoxy-1,2,3,4-tetrahydroquinolin-6-yl)-1H-pyrazol-1-yl)piperidine-1-carboxylate (0.063 g, 0.127 mmol) in dichloromethane (2.0 mL) and the reaction mixture stirred at rt for 1.5 h. The reaction mixture was concentrated and the residue was partitioned between dichloromethane and saturated aqueous sodium bicarbonate solution. The organic phase was separated, dried over anhydrous sodium sulfate, filtered, and concentrated to afford (S)-1-(2-methyl-6-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-5-propoxy-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.045 g, 89%) as a tan solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.91-1.12 (m, 6H), 1.18-1.37 (m, 1H), 1.57-1.88 (m, 5H), 1.97 (br d, J=10.26 Hz, 2H), 2.07 (s, 3H), 2.16-2.40 (m, 2H), 2.53-2.66 (m, 2H), 2.73-2.89 (m, 1H), 3.03 (br d, J=12.61 Hz, 2H), 3.46-3.65 (m, 2H), 4.09-4.30 (m, 1H), 4.62 (br d, J=5.86 Hz, 1H), 7.11 (br d, J=8.21 Hz, 1H), 7.38 (d, J=8.21 Hz, 1H), 7.84 (s, 1H), 8.09 (s, 1H). MS (ESI, pos. ion) m/z 397 [M+H]+.
