Embodiment 1
[0026] N-(N',N'-Dimethylaminoethyl)-4-(4-morpholinomethyl-[1,2,3]-triazole)-1,8-naphthalimide (F1 )Synthesis
[0027] ①In a 50mL two-necked bottle, add 2.50g of 4-bromo-1,8-naphthalene anhydride and 35mL of DMF, stir well at room temperature, and dissolve 0.88g of NaN 3 Dissolve in 2 mL of water, drop into the reaction system, heat to 40°C for 2 hours, pour into cold water after standing, filter with suction, wash with water, and dry to obtain 2.01 g of compound (b) as a yellow-green solid with a yield of 93%.
[0028]
[0029] ②In a 50mL two-necked bottle, add 1g of compound (b) and 30mL of absolute ethanol, stir well at room temperature, add 0.6mL of N,N-dimethylethylenediamine into the reaction system, heat to 50°C for 2h, and statically Pour it into cold water, filter with suction, wash with water, and dry to obtain 1.17 g of compound (c) as a light yellow solid with a yield of 96%.
