Embodiment 1
[0078] Example 1: N-(3-((4-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)pyrimidin-2-yl)amino)-4-methyl Oxyphenyl) propanamide (I-1), prepared by the method of synthetic route 1
[0080] Under ice bath conditions, 2,4-dichloropyrimidine (10.0g, 67.5mmol) was added into 1:1 dichloromethane and methanol (100mL), then potassiumcarbonate (23.3g, 169mmol) and 4,5 , 6,7-Tetrahydrothiopheno[3,2,c]pyridinehydrochloride (11.3 g, 81.0 mmol). React at 0°C for 4 hours. After the reaction was completed, the solvent was evaporated, the residue was added with water, and a solid was precipitated, which was filtered with suction. The crude product was washed with ether, filtered with suction, and the filter cake was dried to obtain 16.7 g of a yellow solid, with a yield of 82.1%.
[0088] Example 2: N-(3-((4-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)pyrimidin-2-yl)amino)4-methoxy phenyl)acrylamide (I-2)
[0089] According to the synthetic method of embodiment 1, intermediate E 1 Compound I-2 of Example 2 was obtained by reacting with acryloyl chloride.
[0090] ESI-MS m / z:408.1[M+H] + .
Embodiment 3
[0091] Example 3: N-(3-((5-chloro-4-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)pyrimidin-2-yl)amino) -4-methoxyphenyl) propionamide (I-3)
[0092]According to the synthesis method of Example 1, 2,4,5-trichloropyrimidine is used as a raw material, and after reacting with 4,5,6,7-tetrahydrothiophene[3,2,c]pyridinehydrochloride, through substitution, Reduction, Intermediate E 1 Compound I-3 of Example 3 was obtained by reacting with propionyl chloride.

Abstract
The invention discloses a compound containing a pyrimidine heterocyclic structure as well as a preparation method and application thereof, belongs to the technical field of medicines, and relates to a compound containing a pyrimidine heterocyclic structure represented by a general formula I and pharmaceutically acceptable salts, hydrates or prodrugs thereof, wherein substituent groups X, Z, R1, R2, R3, A and B have meanings given in the specification. The invention also relates to an effect of inhibiting EGFR kinase and mutants of the compound represented by the general formula I, and also relates to an application of the compound and the pharmaceutically acceptable salts, hydrates or prodrugs thereof in preparation of medicines for treating diseases related to EGFR kinase activity, and in particular, relates to an application in preparation of medicines for treating and / or preventing cancers.
Description
technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a new compound containing a pyrimidine heterocyclic structure and a preparation method thereof, the compound and its pharmaceutically acceptable salt, hydrate, prodrug thereof, or a pharmaceutical composition containing the compound Use in the preparation of medicines for treating diseases related to epidermal growth factorreceptorkinase mutations. Background technique [0002] Epidermal growth factorreceptor (EGFR) regulates the cell cycle and is closely related to cell growth, proliferation and migration. Its coding gene is a proto-oncogene, which is inactive under physiological conditions and has no carcinogenicity. If the gene encoding this receptor is mutated, too much EGFR will be produced, leading to enhanced cell signaling, which can easily induce tumors. Studies have shown that EGFR is highly expressed or abnormally expressed in many solidtumor cells, s...
