Embodiment 1
[0033] Example 1: 2-{1'-N,N-dimethylaminoethyl-4'-acrylamido-7'-methoxy-1',2',3',4'-tetrahydro- 6'-quinoxaline}-4-(1"-methyl-1H-3"-indole)thiophene[2,3-D]pyrimidine (Compound 501)
[0034]
[0035] Preparation of 2-chloro-4-(1'-methyl-1H-3'-indole)thiophene[2,3-D]pyrimidine:
[0036]
[0037] Dissolve 2,4-dichlorothiophene[2,3-D]pyrimidine (0.82g, 4mmol) in ethylene glycol dimethyl ether (20mL), stir under ice bath, add ferric chloride (0.77 g, 4.59mmol), followed by stirring the reaction at room temperature for 15 minutes. Then N-methylindole (0.68 g, 5.2 mmol) was added dropwise, followed by heating to 60° C. and stirring the reaction for 24 hours. Stop the reaction, lower to 0°C, add 3.5mL of methanol and 9mL of water, and then stir the reaction at room temperature for 3 hours. A large amount of solid precipitated, filtered, washed the filter cake with methanol, and dried to obtain 0.81 g of yellow solid, yield: 68%. LC / MS (ESI): m / z 300 (M+H) + .

[0063]
[0064] Preparation of 2-chloro-4-(1'-methyl-1H-3'-indole)thiophene[3,2-D]pyrimidine:
[0065]
[0066]Dissolve 2,4-dichlorothieno[3,2-D]pyrimidine (0.82g, 4mmol) in ethylene glycol dimethyl ether (20mL), stir under ice bath, add ferric chloride (0.77 g, 4.59 mmol), followed by stirring the reaction at room temperature for 15 minutes. Then N-methylindole (0.68 g, 5.2 mmol) was added dropwise, followed by heating to 60° C. and stirring the reaction for 24 hours. Stop the reaction, lower to 0°C, add 3.5mL of methanol and 9mL of water, and then stir the reaction at room temperature for 3 hours. A large amount of solid precipitated, filtered, washed the filter cake with methanol, and dried to obtain a yellow solid, 0.86 g, yield: 72%. LC / MS (ESI): m / z 300 (M+H) + .

Embodiment 3
[0073] Example 3: 2-{1'-N,N-dimethylaminoethyl-4'-butenamido-7'-methoxy-1',2',3',4'-tetrahydro- 6'-quinoxaline}-4-(3"-pyrazol[1,5-a]pyridine)thiophene[2,3-D]pyrimidine (Compound 503)
[0074]
[0075] 2-{1'-N,N-Dimethylaminoethyl-4'-acrylamido-7'-methoxy-1',2',3',4'-tetrahydro-6'-quinoxa Preparation of morpholine}-4-(3"-pyrazol[1,5-a]pyridine)thiophene[2,3-D]pyrimidine (compound 503):
[0076]
[0077] 2-[1'-N,N-Dimethylaminoethyl-7'-methoxy-1',2',3',4'-tetrahydro-6'-quinoxaline]-4-( 3"-pyrazolo[1,5-a]pyridine)thienopyrimidine (390mg, 0.76mmol) and DIPEA (0.146mL, 0.84mmol) were dissolved in dichloromethane (10mL), stirred at 0°C, and then dropped Add crotonoyl chloride (79 mg, 0.76 mmol) dissolved in DCM (2 mL) solution, then stir the reaction for 2 hours. The reaction is complete as detected by TLC. Stop the reaction, add DCM (50 mL), and then use 100 mL of saturated NaHCO 3 Washed with water, the aqueous layer was extracted with DCM (2*50mL), anhydrous MgSO 4 Afte...
