Embodiment 1
[0289] 5-[1-(6-quinolinylmethyl)-1H-[1,2,3]triazol[4,5-b]pyrazin-6-yl]spiro[indoline-3,4' Synthesis of -piperidin]-2-one
[0290]
[0291] Step 1: Synthesis of {2-oxyspiro[indoline-3,4'-piperidinyl]-5-yl}boronic acid pinacol ester
[0292]
[0293] Under nitrogen, add 5-bromospiro[indoline-3,4'-piperidin]-2-one (140.6mg or 0.5mmol), bipinacol borate (140mg or 0.55mmol) and potassium acetate (147mg or 1.5mmol) in DMSO solution (0.2ml) was added PdCl 2 (dppf).CH 2 Cl 2 (20.4 mg or 0.025 mmol), nitrogen was bubbled into the resulting solution for 2 minutes, and then stirred at 80° C. for 16 hours. LC-MS showed that the reaction was complete. After cooling to room temperature, 2 mL of water was added and extracted with DCM (5 mL was used for 3 extractions). Combine the organic phases with Na 2 SO 4 After drying and concentration, 162 mg of the target product was obtained (yield: 98.7%). Mass Spectrum m / z: 328.07 [M+H + ], 329.08[M+H + , 100%], 330.11 [M+H + ].

Embodiment 2
[0297] 6-[1-(6-quinolinylmethyl)-1H-[1,2,3]triazol[4,5-b]pyrazin-6-yl]spiro[indoline-3,4' Synthesis of -piperidin]-2-one
[0298]
[0299] Step 1: Synthesis of {2-oxyspiro[indoline-3,4'-piperidinyl]-6-yl}boronic acid pinacol ester
[0300]
[0301] Referring to the method of Example 1, it was prepared from 6-bromospiro[indoline-3,4'-piperidin]-2-one, yield: 96.9%. Mass Spectrum m / z: 328.07 [M+H + ], 329.08[M+H + , 100%], 330.11 [M+H + ].
[0302] Step 2: 6-[1-(6-Quinolinylmethyl)-1H-[1,2,3]triazol[4,5-b]pyrazin-6-yl]spiro[indoline-3 , Synthesis of 4'-piperidin]-2-one
[0303] Prepare with reference to the method of Example 1. Yield: 73%. Mass Spectrum m / z: 463.23 [M+H + ].
Embodiment 3
[0305]1'-Methyl-5-[1-(6-quinolylmethyl)-1H-[1,2,3]triazol[4,5-b]pyrazin-6-yl]spiro[indole Synthesis of phen-3,4'-piperidin]-2-one
[0306]
[0307] Step 1: Synthesis of 5-bromo-1'-methylspiro[indoline-3,4'-piperidin]-2-one
[0308]
[0309] 5-Bromospiro[indoline-3,4'-piperidin]-2-one (1.686g or 6mmol) was suspended in 15mL THF, cooled to -78°C, and 1M NaN (SiMe 3 ) 2 THF solution (30mL or 30mmol). After the addition was complete, it was stirred at -78°C for 30 minutes, and then solid 2-chloro-N-(2-chloroethyl)-N-methylethylamine hydrochloride (1155 g or 6 mmol) was added. Stirring was continued for 30 minutes after the addition was complete, then raised to room temperature and stirred for two days. TLC showed that the reaction was complete, and 10 mL of 4M hydrochloric acid aqueous solution was carefully added to the pink suspension, then adjusted to pH ≈ 9 with concentrated ammonia water, and extracted with DCM (3 times with 80 mL for each extraction). Combine the ...
