Embodiment 1

[0034] Embodiment 1: the synthesis of target compound Ia

[0035]

[0036] Step 1. The synthesis of 4-(2-fluoro-4-nitrophenyloxy)-6,7-dimethoxyquinoline, the reaction formula is as follows:

[0037]

[0038] Take 4-chloro-6,7-dimethoxyquinoline (6.71g, 30.0mmol) and 2-fluoro4-nitrophenol (5.65g, 36.0mmol) in 60mL of chlorobenzene, and slowly heat to 140°C , Continue to react at this temperature for 20h. Heating was then stopped, cooled to room temperature, and the solvent was evaporated under reduced pressure. The residue was dissolved with dichloromethane, washed with saturated potassium carbonate solution and water successively, dried over anhydrous sodium sulfate, concentrated under reduced pressure, and purified by silica gel column chromatography (PE / EA=3:1), 6.30 g of a light yellow solid was obtained, and the yield was 61%. Mp: 161–163°C.1 H NMR (400MHz, DMSO-d 6 )δ8.56(d, J=5.2Hz, 1H), 8.43(dd, J=2.4, 10.4Hz, 1H), 8.18(d, J=8.8Hz, 1H), 7.60(t, J=8.4Hz, 1H), ...

[0054] Embodiment 3: the synthesis of target compound Ic

[0055]

[0056] The experimental procedure is the same as in Example Ia, except that n-butyraldehyde is used instead of acetaldehyde, and benzoic acid is used instead of thiophene-2-carboxylic acid. White solid, yield: 68.3%. Mp:99-101℃. 1 H NMR (400MHz, DMSO-d 6)δ10.62(s,1H),8.45(d,J=4.8Hz,1H),8.03(d,J=7.6Hz,2H),7.86(d,J=13.2Hz,1H),7.69(t, J=7.6Hz, 1H), 7.58-7.54(m, 2H), 7.52(s, 1H), 7.48-7.41(m, 2H), 7.39(s, 1H), 6.45(d, J=5.2Hz, 1H ),5.19(t,J=7.2Hz,1H),3.93(s,6H),1.98-1.91(m,2H),1.56-1.49(m,2H),0.97(t,J=7.2Hz,3H) . 13 CNMR (100MHz, DMSO-d 6 )δ168.7, 165.5, 159.4, 153.5 (d, J = 244.3Hz), 152.7, 149.5, 148.9, 146.4, 137.6 (d, J = 9.7Hz), 135.8 (d, J = 12.3Hz), 133.8, 129.5 (2C ),129.2,128.9(2C),124.3,116.2(d,J=1.5Hz),114.6,108.2(d,J=22.6Hz),107.9,102.1,99.0,74.2,55.8(2C),33.4,18.3, 13.7.

Description

technical field [0001] The present invention relates to a kind of 4-phenoxyquinolino α-acyloxy amides compound, its intermediate, preparation method and its use as medicine to treat diseases related to tyrosine kinase c-Met, especially c - Use in Met-associated cancer. [0002] Background of the invention [0003] Malignant tumors have always been a serious threat to human life and health, and their effective treatment is still a worldwide problem. In recent years, the advancement of science and technology has gradually clarified the nature of tumors, and people have realized that the essence of cancer is the unlimited proliferation of cells caused by the imbalance of cell signal transduction pathways. As a basic regulatory mechanism of cells, signal transduction transmits various extracellular signals to the inside of cells, so that cells can respond and realize processes such as proliferation, differentiation, and apoptosis. Protein kinases (PKs) are involved in this proce...
