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) triazine (compound 601)
[0034]
[0035] Preparation of 2-chloro-4-(1'-methyl-1H-3'-indole)triazine:
[0036]
[0037] 2,4-dichlorotriazine (0.60g, 4mmol) was dissolved in ethylene glycol dimethyl ether (20mL), stirred under ice bath, ferric chloride (0.77g, 4.59mmol) was added in batches, and then The reaction was stirred 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 0.70 g of yellow solid, yield: 72%. LC / MS (ESI): m / z 245 (M+H) + .

Embodiment 2
[0062] Example 2: 2-{1'-N,N-dimethylaminoethyl-4'-acrylamido-7'-methoxy-1',2',3',4'-tetrahydro- Preparation of 6'-quinoxaline}-4-(1"-methyl-7"-aza-1H-3"-indole)triazine (compound 602):
[0063]
[0064] Preparation of 2-chloro-4-(1'-methyl-7'-aza-1H-3'-indole)triazine:
[0065]
[0066]1-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-B]pyridine ( 0.74g, 2.87mmol) and 2,4-dichlorotriazine (0.51g, 3.44mmol) were dissolved in ethylene glycol dimethyl ether (20mL), then dichlorodi-tert-butyl-(4-dimethyl Aminophenyl)phosphine palladium(II) (0.31g, 0.19mmol), 2M sodium carbonate solvent (3.2mL, 6.3mmol). Under nitrogen protection, stirred and heated to 80°C for 4 hours. The reaction was complete as detected by TLC. The reaction was stopped and diluted with water (1 mL). Ethyl acetate (25mL) extracted twice, anhydrous MgSO 4 After drying and concentration, the crude product was separated by flash column to obtain 457 mg of yellow solid, yield: 65%. ...
Embodiment 3
[0073] Example 3: 2-{1'-N,N-Dimethylaminoethyl-4'-acrylamido-7'-methoxy-1',2',3',4'-tetrahydro-6 '-quinoxaline}-4-(3"-pyrazol[1,5-a]pyridine)triazine (compound 603)
[0074]
[0075] Preparation of 2-chloro-4-(1'-methyl-1H-3'-indole)triazine:
[0076]
[0077] Pyrazolopyridine (1,5,-A)-3-boronate (0.70 g, 2.87 mmol) and 2,4-dichlorotriazine (0.51 g, 3.44 mmol) were dissolved in ethylene glycol dimethyl ether (20 mL), then dichlorodi-tert-butyl-(4-dimethylaminophenyl)phosphine palladium (II) (0.13 g, 0.19 mmol), 2M sodium carbonate solvent (32 mL, 6.3 mmol) was added with stirring. Under nitrogen protection, stir and heat to 80° C. for 4 hours. The reaction was complete as detected by TLC. The reaction was quenched and diluted with water (2 mL). Ethyl acetate (25mL) extracted twice, anhydrous MgSO 4 After drying and concentration, the crude product was separated by flash column to obtain 378 mg of yellow solid, yield: 57%. LC / MS (ESI): m / z 232 (M+H) + .
