With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In 1,4-dioxane; water; at 110℃; for 1h;Microwave irradiation; | To a mixture of 4-amino-2-nitrophenylboronic acid (606 mg, 3.30 mmol, 90%), 2-bromo-1,3-difluoro-benzene (579 mg, 3.00 mmol) and Pd(PPh3)4 (347 mg, 0.300 mmol) in 1,4-dioxane (9 mL) was added 2.0 M aqueous Na2CO3 (6.00 mL, 12.0 mmol). The resulting mixture was stirred at 110 C. under microwave irradiation for 1 h and then cooled to room temperature. The resulting mixture was treated with EtOAc (50 mL), then was washed with H2O and brine and was dried (Na2SO4). The solvent was removed under reduced pressure followed by flash chromatography of the residue on silica gel (5-40% EtOAc-hexanes) to yield a yellow solid. 1H-NMR (400 MHz, CDCl3) delta: 8.30 (s, 1H), 7.50 (dd, J=8.6, 1.8 Hz, 1H), 7.23-7.34 (m, 1H), 6.95-7.05 (m, 1H), 6.90 (d, J=8.6 Hz, 1H), 6.19 (br. s., 2H).
