实验步骤: Following the procedure described for N-[2-(2,6-dichlorophenyl)-2H-pyrazolo[4,3-c]pyridine-4-yl]-N′-methylpyrimidine-4,6-diamine, (6-chloropyrimidin-4-yl)-[2-(2,6-dichlorophenyl)-2H-pyrazolo[4,3-c]pyridine-4-yl]amine and 3-fluoroazetidine with added DIPEA (103 μL, 0.6 mmol) were reacted to afford the title compound as a yellow solid (81 mg, 93% yield). 1H NMR (400 MHz, DMSO-d6): δ 10.28 (br s, 1H), 9.14 (s, 1H), 8.29 (s, 1H), 7.94 (s, 1H), 7.80 (d, J=8.1 Hz, 2H), 7.70 (dd, J=9.1, 7.3 Hz, 2H), 7.16 (br s, 1H), 5.62-5.46 (m, 1H), 4.38 (ddd, J=21.3, 10.5, 5.9 Hz, 2H), 4.14 (d, J=10.5 Hz, 1H), 4.08 (d, J=10.5 Hz, 1H). LCMS (Method B): RT=3.16 min, m/z: 430 [M+H+]. were reacted

实验步骤: A mixture of 2-(2-chloro-11-fluoro-5,6-dihydroindolo[1,2-h][1,7]naphthyridin-6-yl)acetaldehyde (200 mg, 0.617 mmol) and 3-fluoroazetidine (95 mg, 1.23 mmol) in DCM (4 mL) was stirred at room temperature for 30 minutes under N2. Then Na(OAc)3BH (50 mg) was added to the mixture, and the mixture was stirred at room temperature for 1 hour. After dilution with water (30 mL) and extraction with EA (20 mL×3), the organic layer was washed with brine (30 mL*3), dried over Na2SO4 and concentrated. The residue was purified by column chromatography (PE:EA=1:1) to afford the desired product of 2-chloro-11-fluoro-6-(2-(3-fluoroazetidin-1-yl)ethyl)-5,6-dihydroindolo[1,2-h][1,7]naphthyridine (100 mg, yield: 43%). 1H-NMR (CDCl3, 400 MHz) δ 7.44 (d, J=8.0 Hz, 1H), 7.3 (s, 1H), 7.16 (d, J=8.0 Hz, 1H), 7.10 (t, J=4.8 Hz, J=2.7 Hz, 2H), 6.69˜6.74 (m, 1H), 5.11˜5.14 (m, 0.5H), 4.97˜4.50 (m, 0.5H), 4.87 (t, J=4.8 Hz, 1H), 3.57 (d, J=6.8 Hz, 1H), 3.33˜3.39 (m, 1H), 2.95˜3.06 (m, 2H), 2.2˜72.38 (m, 1H). MS (M+H)+: 374/376. the mixture was stirred at room temperature for 1 hour After dilution with water (30 mL) and extraction with EA (20 mL×3) the organic layer was washed with brine (30 mL*3) dried over Na2SO4 concentrated The residue was purified by column chromatography (PE:EA=1:1)
