実験手順

To a stirred solution of compound 23 (458 mg, 1.40 mmol) in Ph2O (6 mL) was added 2-fluoro-4-nitrophenol (242 mg, 1.54 mmol). The reaction mixture was heated at 120° C. for 2.5 hours, treated with K2CO3 (80 mg, 0.56 mmol) and heated at the same temperature for additional 18 hours. After cooling, the reaction mixture was purified by flash chromatography on a silica gel column (eluents EtOAc-hexane 5:95, 1:1, then MeOH-DCM, 5:95 and 1:9), to afford the title compound 24 (570 mg, 91% yield) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ(pm): 9.09 (t, J=5.6 Hz, 1H), 8.77 (s, 1H), 8.41 (dd, J=2.4 and 10.4 Hz, 1H), 8.30 (s, 1H), 8.22 (dd, J=2.4 and 8.8 Hz, 1H), 7.88 (t, J=8.8 Hz, 1H), 3.60-3.52 (m, 4H), 3.45 (q, J=6.8 Hz, 2H), 2.50 (q, J=6.8 Hz, 2H), 2.46-2.40 (m, 4H).
