Embodiment 1
[0075] Example 1: N-(1-(2-(dimethylamino)ethyl)-5-((4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl)amino) -1H-indazol-7-yl)acrylamide (I-1)
[0076]
[0077] The synthetic route is as follows:
[0078]
[0079] Step 1. Preparation of 5,7-dinitro-1H-indazole (2):
[0080] Under ice bath, 5-nitro-1H-indazole (1) (16.32g, 100mmol) was dissolved in sulfuric acid solution, and concentrated nitric acid (40ml, 400mmol) was added dropwise under ice bath. After the reaction was completed, the reaction solution was Slowly pour into ice water, stir well, and filter with suction to obtain 20.61 g of white filter cake of 5,7-dinitro-1H-indazole (2), with a yield of 99%. 1 H NMR (400 MHz, DMSO- d 6 ) δ 14.57(s, 1H), 9.30 (d, J = 2.0 Hz, 1H), 8.95 (d, J = 2.0 Hz, 1H), 8.70 (s, 1H).
[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).
