[0081] Step 2. Preparation of 2-(5,7-dinitro-1H-indazol-1-yl)-N,N-dimethyl-1-ethylamine (3):

[0082]Dissolve 5,7-dinitro-1H-indazole (2) (10.41g, 50mmol) in THF, add sodium hydrogen (1.44g, 60mmol) un...

Embodiment 2

[0095] Example 2: (E)-N-(1-(2-(Dimethylamino)ethyl)-5-((4-(1-methyl-1H-indol-3-yl)pyrimidine-2- Base)amino)-1H-indazol-7-yl)-2-butenamide (I-2)

[0096]

[0097] Referring to the synthetic method of (I-1), the yield was 66%. 1 H NMR (400 MHz, DMSO- d 6 ) δ 11.26 (s, 1H),8.38 (d, J = 8.0 Hz, 1H), 8.35 (d, J = 5.3 Hz, 1H), 8.19 – 7.99 (m, 3H), 7.93(s, 1H), 7.37 (d, J = 8.2 Hz, 1H), 7.33 – 7.27 (m, 1H), 7.24 – 7.21 (m, 1H),7.13 – 7.07 (m, 1H), 7.05 (s, 1H), 6.06 (d, J = 15.2 Hz, 1H), 4.69 (dd, J =5.9, 3.6 Hz, 2H), 3.89 (s, 3H), 2.92 (s, 2H), 2.24 (s, 6H), 1.95 (d, J = 6.9Hz, 3H).

Embodiment 3

[0098] Example 3: N-(1-(2-(dimethylamino)ethyl)-5-((4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl)amino) -1H-indazol-7-yl)-3-methyl-2-butenamide (I-3)

[0099]

[0100] Referring to the synthetic method of (I-1), the yield is 57%. 1 H NMR (400 MHz, Chloroform- d ) δ 11.18(s, 1H), 8.41 (dt, J = 7.8, 1.0 Hz, 1H), 8.35 (d, J = 5.3 Hz, 1H), 8.12 –7.91 (m, 4H), 7.39 – 7.28 (m, 2H), 7.25 – 7.18 (m, 2H), 7.05 (d, J = 5.4 Hz,1H), 5.86 – 5.80 (m, 1H), 4.71 – 4.66 (m, 2H), 3.88 (s, 3H), 2.90 (s, 2H),2.29 (d, J = 1.3 Hz, 3H), 2.24 (s, 6H), 1.94 (s, 3H).

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and specifically relates to 2-aminomeridine compounds and their preparation methods and applications. Background technique [0002] EGFR (epidermal growth factor receptor, referred to as EGFR, ErbB-1 or HER1) is a member of the epidermal growth factor receptor (HER) family, a transmembrane receptor located on the surface of the cell membrane, with a molecular weight of 170KDa, activated by binding to ligands , including EGF and TGFα (transforming growth factor α); further, activate intracellular kinase pathways, including Y992, Y1045, Y1068, Y1148 and Y1173 alleles, guide the phosphorylation of downstream MAPK, Akt and JNK pathways, and induce cell proliferation . The activation of EGFR can be divided into three steps: (1) EGFR can lead to the formation of homodimers after binding with ligands, and can also form heterodimers with other EGFR families; (2) dimerization Phosphorylation of 6 s...
