Embodiment 1
[0071] Embodiment 1: the synthesis of compound 2T6
[0072] Dissolve 0.3mol of chloroacetic acid in 60ml of water, adjust the pH to 9 with sodium hydroxide, then add 0.2mol of phenol, and reflux at 100°C to obtain compound T1, then add thionyl chloride for chlorination reaction to obtain compound T2, steam Thionyl chloride solvent was removed to obtain a brown liquid, which was then condensed with anthranilic acid to obtain T3, and then PPA was preheated to 130°C and added to T3 for a compound reaction to obtain compound T4, and T4 was mixed with thionyl chloride at 80 Chlorination reaction was carried out at reflux at ℃ to obtain compound T5, and then the purified T5 was added to a single-necked bottle, and phenol was added to react overnight at 60°C, then 1,4-butanediamine was added to react at 120°C for 12 hours, and finally the product was passed through silica gel Column purification yielded compound 2T6.
[0073] Yield: 82%; Melting point: 158-159°C; 1 HNMR: (400MHz, C...
Embodiment 2
[0076] Embodiment 2: the synthesis of compound 4T7
[0077] Dissolve 0.3mol of chloroacetic acid in 60ml of water, adjust the pH to 9 with sodium hydroxide, then add 0.2mol of p-methoxyphenol, and reflux at 100°C to obtain compound T1, and then add thionyl chloride for chlorination reaction to obtain For compound T2, distill off the thionyl chloride solvent to obtain a brown liquid, then perform condensation reaction with anthranilic acid to obtain T3, then preheat PPA to 130°C and add T3 for compound reaction to obtain compound T4, and combine T4 with chlorinated Sulfoxide was refluxed at 80°C for chlorination reaction to obtain compound T5, and then the purified T5 was methylated with methyl iodide in a sulfolane solvent system to obtain compound T6, and T6-2 was added to a single-necked bottle , using ethylene glycol ether as a solvent, and reacting with N,N-bis(3-aminopropyl)methylamine at 120°C for 30 minutes, and finally adding a large amount of anhydrous ether, precipit...
Embodiment 3
[0081] Embodiment 3: the synthesis of compound 5T8
[0082] The method is the same as in Example 2, except that T5 is used as a solvent in dichloromethane, and boron tribromide is used to remove the methyl group in the methoxy group to obtain compound T6-1. React with N,N-dimethylethanolamine under anaerobic conditions, obtain compound T7-1 after purification by silica gel column, add T7-1 into a single-necked bottle, and add phenol to react overnight at 60°C, then add 1, 4-Butanediamine was reacted at 120° C. for 12 h, and finally the product was purified by silica gel column to obtain compound 5T8.
[0083] Yield: 84%; Melting point: 176-177°C; 1 HNMR: (400MHz, CDCl 3 )δ8.15(d,J=8.3Hz,1H),7.94(d,J=8.4Hz,1H),7.78(d,J=2.5Hz,1H),7.61(t,J=7.2Hz,1H) ,7.42-7.36(m,2H),7.19(dd,J=8.9,2.6Hz,1H),5.73(s,1H),4.14(t,J=5.6Hz,2H),3.99(t,J=6.5 Hz, 2H), 2.80-2.74(m, 4H), 2.34(s, 6H), 1.87-1.76(m, 2H), 1.67-1.60(m, 2H); ESI+APCI-MSm / z: 393[M +H] + .
