Embodiment 2
[0040] Compound 2-(benzo[d]thiazol-2-yl)-4-(1-(phenyl)imidazoline-2-ylidene)-4-nitrobutyl- 2-alkene nitrile, its preparation method is:
[0041]
[0042] Using N-phenylethylenediamine as the starting material, referring to the method disclosed in the patent WO2004058714A1, successively undergoes a substitution reaction with 1,1-dithiomethyl-2-nitroethylene, and then reacts with N,N-dimethyl The intermediate 2-(1-(phenyl)imidazolin-2-ylidene)-2-nitroacetaldehyde (M-1) was prepared by condensation reaction of methyl formamide dimethyl acetal and alkaline hydrolysis reaction. Then weigh M-1, that is, 2-(1-(phenyl)imidazoline-2-ylidene)-2-nitroacetaldehyde 0.12g (0.5mmol) and dissolve it in 10mL absolute ethanol. Add 0.096g (0.55mmol) of 2-cyanomethylbenzothiazole (compound A) and a catalytic amount of potassium hydroxide, stir the reaction mixture at room temperature for 30 minutes, then slowly heat to 40-45°C, keep warm for reaction, and monitor by TLC until the reaction is...
Embodiment 3
[0044] Compound 2-(benzo[d]oxazol-2-yl)-4-(1-((6-chloropyridin-3-yl)methyl)imidazoline-2 numbered as I-37 in Example 1 -subunit)-4-nitrobut-2-enenitrile, its preparation method is:
[0045]
[0046] Using 2-chloro-5-chloromethylpyridine as the starting material, it undergoes the substitution reaction with ethylenediamine, the substitution reaction with 1,1-dithiomethyl-2-nitroethylene, and then with N,N -Dimethylformamide dimethyl acetal condensation reaction, alkaline hydrolysis reaction to prepare intermediate 2-(1-((6-chloropyridin-3-yl)methyl)imidazoline-2-ylidene)-2 - Nitroacetaldehyde (M-2). Then weigh M-2, 0.14g (0.5mmol) of 2-(1-((6-chloropyridin-3-yl)methyl)imidazolin-2-ylidene)-2-nitroacetaldehyde in 10mL In absolute ethanol, at room temperature, 0.087 g (0.55 mmol) of 2-cyanomethylbenzoxazole (compound B) and a catalytic amount of piperidine were added successively, and the reaction mixture was first stirred at room temperature for 30 minutes, and then slowly h...
