실험 절차

An oven-dried conical flask was charged with 4-(3-bromo-5-chlorophenyl)-morpholine (0.384 g, 1.390 mmol) and 1.0 mL THF. While this solution was stirring at −78° C. under nitrogen, 2.5M butyllithium hexanes (0.556 mL, 1.390 mmol) was added via syringe. This solution was stirred at −78° C. for 30 minutes. After this time a solution of 7-fluoro-3-methyl-2-(pyridin-2-yl)quinoline-4-carbaldehyde (0.074 g, 0.278 mmol) in 2.0 mL THF was added, and the reaction continued at −78° C. for 45 minutes. Upon completion, the reaction was quenched with satd aqueous ammonium chloride and concd. The resulting material was partitioned between EtOAc and water, and the organic phase was dried over magnesium sulfate and concd. The afforded crude product was purified by column chromatography (silica; 0-50% EtOAc in hexanes) to yield (3-chloro-5-(4-morpholinyl)phenyl)(7-fluoro-3-methyl-2-(2-pyridinyl)-4-quinolinyl)methanol as a white amorphous solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.70 (1H, d), 8.35 (1H, m), 8.01 (1H, t), 7.83 (1H, s), 7.71 (1H, d), 7.51 (1H, m), 7.42 (1H, m), 6.97 (1H, s), 6.83 (1H, s), 6.64 (1H, d, J=4.5 Hz), 6.55 (1H, d), 6.51 (1H, s), 3.69 (4H, t, J=4.8 Hz), 3.08 (4H, d, J=3.9 Hz), 2.46 (3H, s). Mass Spectrum (ESI) m/e=464.0 (M+1).
