[0521] Preparation example 1 (raw material 1)

[0522] Add 7-(benzyloxy)-4-chloro-6-methoxyquinoline (29g), 3-fluoro-4-nitrophenol (20g), N,N-diisopropylethylamine (33ml) , Chlorobenzene (14ml), heated and stirred at 140°C for 15 hours. After completion of the reaction, 2N aqueous sodium hydroxide solution (30 ml) was added, followed by stirring at room temperature for 3 hours. Water was added to the reaction liquid, extracted with chloroform, and the chloroform layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 40 g of the target compound in a yield of 50%.

The compounds of the present invention are represented by formula (I) or a pharmaceutically acceptable salt or solvate thereof: wherein X=CH or N; Z=O or S; L=O or S; M=CR10R11, wherein R10 and R11 =H, alkyl, or alkoxy, NR12 wherein R12=H or alkyl; R1, R2, and R3=H or optionally substituted alkoxy; R4=H; R5-R8=H, halogen, alkoxy or the like; and R9=alkyl optionally substituted by -R14, -T-R15, or -NR16R17 wherein T=O, S, or NH; R14 =an optionally substituted carbocyclic or heterocyclic ring; and R15-R17=alkyl or an optionally substituted carbocyclic or heterocyclic ring, or -NR18R19 wherein R18 and R19 =H, optionally substituted alkyl, or an optionally substituted carbocylic or heterocyclic ring, or optionally substituted carbocyclic or heterocyclic ring.

Description

technical field [0001] The present invention relates to quinoline derivatives and quinazoline derivatives with anti-tumor effect, more specifically, to the effect of inhibiting the autophosphorylation of hepatocyte growth factor receptor, and the inhibitory effect on abnormal cell proliferation or cell movement quinoline derivatives and quinazoline derivatives. Background technique [0002] Growth factors such as epithelial growth factor, platelet-derived growth factor, insulin-like growth factor, and hepatocyte growth factor (Hepatocyte Growth Factor, hereinafter referred to as "HGF") play an important role in cell proliferation. Among them, HGF is known as Liver regeneration factor and kidney regeneration factor are related to the regeneration of injured liver and kidney (Oncogenesis, 3, 27 (1992)). [0003] However, overexpression of HGF or its receptor (hereinafter referred to as "met") in various tumors such as brain tumors, lung cancer, gastric cancer, pancreatic can...
