Embodiment 1
[0160] The preparation of embodiment 1 compound of the present invention
[0161]
[0162] Take compound 1-1 (1.86g, 10mmol), compound 2-1 (3.17g, 12mmol), Pd(dppf)Cl 2 (5mmol%), potassium carbonate (2.76g, 20mmol), add 1,4-dioxane and water (volume ratio is 4:1) in the mixed solvent 50mL, N 2 After the replacement, the reaction was carried out at 100° C. for 6 hours. The reaction was monitored by TLC. After the reaction was complete, the reaction solution was distilled off under reduced pressure, and the residue was dissolved in a mixed solvent of dichloromethane and methanol, filtered through diatomaceous earth, and the filtrate was concentrated, followed by column chromatography (PE:EA=2:1) Intermediate I-1 was obtained (pale yellow solid, 73%), MS m / z (ESI): 244.1 [M+H] + .
[0163]
[0164] Intermediate Ⅰ-1 (1.21g, 5mmol) was dissolved in 30mL of toluene, potassium acetate (0.59g, 6mmol), acetic anhydride (0.94mL, 10mmol) were added, stirred at room temperature f...
Embodiment 2
[0192] The preparation of embodiment 2 compounds of the present invention
[0193]
[0194] Take compound 4-4 (50 mg), add 10 ml of HCl / 1,4-dioxane solution, stir at room temperature for 5 h, concentrate the solvent, dissolve the residue in methanol and perform thin-layer chromatography (DCM:MeOH=8: 1) Obtain compound 4-5 (light brown solid, 52%). 1 H NMR (400MHz, DMSO-d 6 )δ9.58(s,2H),8.26(d,J=8.5Hz,1H),7.83(d,J=7.9Hz,2H),7.77(s,1H),7.68(d,J=16.7Hz, 1H), 7.58(d, J=16.7Hz, 1H), 7.51(dd, J=7.9, 4.4Hz, 3H), 6.87(d, J=2.2Hz, 2H), 6.55(t, J=2.2Hz, 1H), 3.84(s,6H), 3.78–3.63(m,4H), 3.16(s,4H).
[0195] Using a similar method the following compounds can be obtained:
[0196] Compound 4-7
[0197]
[0198] 1H NMR (400MHz, DMSO-d6) δ13.35(s, 1H), 8.28(d, J=8.5Hz, 1H), 7.84–7.78(m, 3H), 7.66(d, J=16.8Hz, 1H) ,7.61–7.51(m,2H),7.40(d,J=8.0Hz,2H),7.23–7.13(m,2H),6.87(dt,J=10.9,2.3Hz,1H),3.87(s,6H ),3.63–3.35(m,3H),2.69(d,J=8.5Hz,3H),1.10–0.80(m,7H).
