Reaction Steps

A mixture of 160 mg (0.60 mmol) of methyl 7-bromo-4-quinolinecarboxylate, 200 mg (0.90 mmol) of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol, 7 mg (0.03 mmol) of palladium(II)acetate, 16 mg (0.06 mmol) of triphenylphosphine, 450 mg (2.10 mmol) of K3PO4 and 50 uL (3.01 mmol) of H2O in 3 mL of dioxane was stirred at 60° C. for 1.5 hr. EtOAc was added then the organics were washed with H2O and brine then concentrated. The residue was suspended in cold EtOAc and the solids were collected by suction filtration, washed with cold EtOAc and dried to give 92 mg (55%) of methyl 7-(4-hydroxyphenyl)-4-quinolinecarboxylate as a tan solid. 1H NMR (400 MHz, CDCl3): δ 9.75 (s, 1H), 9.03 (s, 1H), 8.63 (d, J=9 Hz, 1H), 8.25 (d, J=2 Hz, 1H), 8.03 (dd, JA=2 Hz, JB=9 Hz, 1H), 7.87 (s, 1H), 7.72 (d, J=8 Hz, 2H), 6.90 (d, J=8 Hz, 2H), 3.98 (s, 3H). ESI-LCMS m/z 280 (M+H)+.
