Problems solved by technology

However, these molecules have poor selectivity to the T790M mutant of EGFR, resulting in a low clinically tolerated dose of the drug. At its maximum tolerated dose (MTD), the drug cannot reach its effective concentration in the body, making it ineffective for most drug-resistant patients
[0004] In short, the current EGFR-TKI still cannot solve the clinical needs caused by drug resistance, and most of the existing drugs are EGFR reversible or irreversible inhibitors based on quinazoline or quinolineamine Toxic side effects caused by poor selectivity of wild-type cells are also inevitable
Therefore, there is an urgent need for new types of compounds, especially compounds with novel skeletons, to solve problems such as drug resistance and poor selectivity.

[0122]

[0123] The synthetic route is as follows:

[0124]

[0125] Compound FHND004‐05‐2

[0126] Take 120mL sealed tube, add (FHND004‐05‐1) (2.0g, 4.77mmol), 1‐methylpiperazine (477.16mg, 4.77mmol), DIPEA (0.92g, 7.16mmol), DMA (10mL). Then the tube was sealed and reacted at 140°C for 6 hours. TLC monitored that there was no raw material remaining. The reaction liquid was cooled to room temperature, 20 mL of water was added to precipitate a solid, filtered, and then the filter cake was added to 2 mL of methanol for beating and washing, filtered, and dried to obtain a red solid product ( FHND004-05-2) 1.9g.

Abstract

The invention discloses 3-(4,5-substituted pyrimidinamine) phenyl derivatives and application thereof. The 3-(4,5-substituted pyrimidinamine) phenyl derivatives are compounds having a structure as shown in a formula (I) or pharmacologically acceptable salts of the compounds; the compounds or the salts thereof can be used for treating or preventing diseases or states of illnesses by means of certain mutant forms of epidermal growth factor receptors (EGFRs), can effectively inhibit the growth of multiple tumor cells and have an inhibiting effect for other protease of EGFR and Her families, thus being used for preparing antitumor drugs. The formula I is described in the description.

Description

technical field [0001] The invention belongs to the technical field of antineoplastic drugs, and in particular relates to 3-(4,5-substituted aminopyrimidine) phenyl derivatives and their application in the preparation of antineoplastic drugs. Background technique [0002] In the traditional cancer treatment process, chemotherapy is the main treatment method; chemotherapy drugs non-specifically block cell division and cause cell death. While killing tumor cells, they also greatly destroy the growth of normal human cells, resulting in Many adverse reactions. Many people feel pessimistic or even give up treatment because they are worried about the serious side effects of chemotherapy. Coupled with the drug resistance of chemotherapy drugs, the chemotherapy of non-small cell lung cancer (NSCLC) is not optimistic, and prolonging the cycle of chemotherapy will only increase the toxicity and side effects. did not increase efficacy. At the same time, cancer cells of non-small cell...
