実験手順

To a stirred solution of 5-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzamide (5.0 g, 10 mmol) and (4-formylphenyl) boronic acid (2.35 g, 15.8 mmol) in dioxane/water (30 mL/10 mL) was added Na2CO3 (4.01 g, 37.9 mmol). The solution was purged with argon for 15 min., Pd(PPh3)4 (1.21 g, 1.05 mmol) and the mixture was heated at 100° C. for 2 h. The mixture was allowed to cool to room temperature, diluted with water and extracted with 10% MeOH/CH2Cl2. The combined organic layers were dried over sodium sulphate and the solvent removed under reduced pressure. The resulting crude material was purified by column chromatography over silica gel to afford N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-4′-formyl-4-methyl-[1,1′-biphenyl]-3-carboxamide (3.5 g, 66%).
