実験手順

A mixture of N-{[3-bromo-4-(methyloxy)phenyl]methyl}-N′-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}propanediamide (0.800 g, 1.362 mmol), (3-formylphenyl)boronic acid (0.225 g, 1.5 mmol), tetrakis (triphenylphosphine) palladium (0) (0.058 g, 0.05 mmol), sodium carbonate (0.371 g, 3.5 mmol), and 1,4-dioxane (12 ml) and water (4 ml), with stirring under N2, was microwaved at 140° C. for 30 minutes. The reaction mixture was diluted with EtOAc and water and the organic layer taken off. It was washed with saturated NaCl, dried over Na2SO4, and evaporated resulting in a viscous taffy. The viscous taffy was purified on a Chromatotron Plate Silica Gel (1000μ) eluting with CH2Cl2— MeOH (97:3) to afford N-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-N′-{[3′-formyl-6-(methyloxy)-3-biphenylyl]methyl}propanediamide (526 mg, 91%) as a viscous, nearly colorless, taffy. LC-MS m/z 613.4 (M+H)+, 0.81 min (ret time).
