実験手順
To a solution of 3-(2,2-dipyridin-3-ylethyl)-N-methyl-N-pyridin-3-ylpyridin-2-amine (34 mg) in 1.2 mL of DMSO:t-BuOH (80:20) was added potassium tert-butoxide (21 mg). The reaction was stirred under an oxygen balloon at room temperature for 2 h, then quenched by adding 2 drops of water. Purification by reverse phase HPLC gave 26 mg of 2-{2-[methyl(pyridin-3-yl)amino]pyridin-3-yl}-1,1-dipyridin-3-ylethanol as a white solid. 1H NMR (500 MHz, CDCl3): δ 8.54 (d, J=1.9 Hz, 2H), 8.47 (dd, J=4.6, 1.7 Hz, 2H), 8.35 (dd, J=4.6, 1.7 Hz, 1H), 8.21 (dd, J=4.6, 1.2 Hz, 1H), 8.05 (d, J=2.7 Hz, 1H), 7.59-7.57 (m, 2H), 7.24-7.15 (m, 4H), 7.08-7.05 (m, 1H), 6.99-6.95 (m, 1H), 4.57 (s, 1H), 3.55 (s, 2H), 3.21 (s, 3H).
