実験手順

350 mg of 1′-[(4,8-dimethoxyquinolin-2-yl)carbonyl]-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)spiro[chroman-2,4′-piperidin]-4-one, 151 mg of 5-bromonicotinamide, 72.5 mg of Pd(PPh3)4 and 1.4 mL of 2M Na2CO3aq were heated with 1,4-dioxane at 100° C. and stirred for 21 hours. The reaction solution was diluted with CHCl3, filtered through Celite, and the filtrate was dried with magnesium sulfate and concentrated. The residue was purified through silica gel thin-layer chromatography (CHCl3/MeOH=9/1) to obtain the intended compound. 1H-NMR (400 MHz, CDCl3) δ: 8.90-9.00 (2H, m), 8.36 (1H, s), 8.15 (1H, s), 7.70-7.80 (2H, m), 7.40-7.55 (1H, m), 7.19 (1H, s), 7.17 (1H, d, J=8.8 Hz), 7.09 (1H, d, J=7.8 Hz), 6.3-6.5 (1H, br), 5.7-6.1 (1H, br), 4.50-4.60 (1H, m), 4.10-4.15 (1H, m), 4.08 (3H, s), 4.03 (3H, s), 3.55-3.70 (1H, m), 3.35-3.50 (1H, m), 2.88 (1H, d, J=16.6 Hz), 2.82 (1H, d, J=16.6 Hz), 2.20-2.30 (1H, m), 2.05-2.15 (1H, m), 1.80-2.05 (2H, m). MS [M+H]+=553.
