[0665] (Preparation Example 1) tert-butyl 3-dimethylaminoazetidine-1-carboxylate

[0666]To a solution of 1-Boc-azetidin-3-one (3.45 g) in methanol (175 ml) was added 2M dimethylamine-tetrahydrofuran solution (21.9 ml), acetic acid (1.73 ml), 10% palladium on carbon ( 2.15 g), stirred at room temperature in a hydrogen atmosphere for 14 hours. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure. The residue was partitioned between ethyl acetate-saturated aqueous sodium bicarbonate. The combined organic layers were dried over anhydrous sodium sulfate. It was concentrated to obtain the title compound (4.07 g, 101%) as a colorless oil.

Abstract

General formula (I) (wherein, R 1 It is a 3- to 10-membered non-aromatic heterocyclic group or the like. R 2 and R 3 for a hydrogen atom. R 4 , R 5 , R 6 and R 7 Same or different, hydrogen atom, halogen atom, C 1－6 Alkyl etc. R 8 for hydrogen atoms, etc. R 9 It is a 3- to 10-membered non-aromatic heterocyclic group or the like. n is an integer of 1-2. X is a group represented by the formula -CH= or a nitrogen atom. ) or their salts or their hydrates have excellent hepatocyte growth factor receptor (HGFR) inhibitory activity, and exhibit antitumor activity, angiogenesis inhibitory activity or cancer metastasis inhibitory activity.

Description

technical field [0001] The present invention relates to novel pyridine derivatives and pyrimidine derivatives or their salts or their hydrates, which have hepatocyte growth factor receptor inhibitory effects, antitumor effects, angiogenesis inhibitory effects, and cancer metastasis inhibitory effects. Background technique [0002] It has been reported that hepatocyte growth factor receptor (hepatocyte growth factor receptor; ”) overexpression (Non-Patent Document 1). It is generally believed that the HGFR expressed in the above-mentioned tumor cells is often stimulated by hepatocyte growth factor (hepatocyte growth factor; hereinafter referred to as "HGF") to cause autophosphorylation of tyrosine kinase in the intracellular region, so it is related to cancer malignancy. (Abnormal proliferation, invasion or metastatic hyperfunction). [0003] In addition, it has been reported that HGFR is also expressed in vascular endothelial cells, and HGF stimulates HGFR to promote the p...
