Embodiment 1
[0048] 1′-Thio-7′-azaidirubin
[0049] Add 20mL methanol, isatin (76mg, 0.52mmol), thieno[2,3-b]pyridin-3-one (78mg, 0.52mmol) and anhydrous sodium carbonate (137mg, 1.29mmol) successively in a 50mL single-necked flask , stirred at room temperature for 6 h under nitrogen protection, and brown flocculent precipitates gradually precipitated. After filtration, the filter cake was washed successively with 50 mL of methanol, 50 mL of distilled water and 50 mL of methanol, and dried to obtain 125 mg of brown flocculent solid, yield 86.4%, mp>300°C. 1 H-NMR (300MHz, DMSO, δppm): 11.20 (s, 1H, NH), 8.99 (d, 1H, J=8.1Hz, H-4), 8.79 (dd, 1H, J=1.5Hz, 4.5Hz, H-6'), 8.22(dd, 1H, J=1.5Hz, 7.8Hz, H-4'), 7.40-7.49(m, 2H, H-6, 5'), 7.10(t, 1H, J= 8.1 Hz, H-5), 6.96 (d, 1H, J=7.8 Hz, H-7). IR (cm -1 , KBr): 3128, 3059, 1709, 1674, 1612, 1573, 1462, 1399, 1332, 1293, 1286, 1223, 1059, 1025, 1003, 761, 750, 740. ESI-MSm / z: 281.16[M+H] + .
