実験手順
A solution mixture of 3a (0.13 g, 0.75 mmol), 9 (0.27 g, 0.9 mmol) and piperidine (0.1 mL) in ethanol (30 mL) was heated to reflux overnight. After cooling down to room temperature, the organic solvent was removed by rotary evaporation. The residue was purified by recrystallization from methanol affording SPOH (0.18 g) as pale red solid in 53% yield. NMR (400 MHz, DMSO-d6) δ 8.88 (d, J=6.8 Hz, 2H), 8.55 (s, 1H), 8.19 (m, 4H), 7.84 (d, J=8 Hz, 1H), 7.65 (m, 2H), 7.49 (m, 2H), 7.25 (t, J=7.2 Hz, 1H), 5.66 (s, 1H), 4.57 (m, 4H), 3.79 (m, 4H), 3.43 (m, 2H), 3.27 (m, 2H), 3.08 (s, 3H). 13C NMR (400 MHz, DMSO-d6) δ 153.4, 144.4, 142.4, 141.7, 140.8, 126.4, 126.3, 126.2, 122.7, 122.6, 122.1, 121.1, 120.3, 120.0, 119.7, 110.4, 110.2, 71.2, 69.8, 68.8, 61.6, 600.1, 58.1, 42.8.
