Embodiment 1
[0020] N-(1-ethylpyrrolidine-2-methyl)-2-(5-hydroxyl-4-oxygen-2-phenyl-4H-benzopyrone-7-oxyl)acetamide preparation (1 ), the preparation of ethyl 2-(5-hydroxy-2-phenyl-4H-benzopyrone-7-oxo)acetate
[0021]
[0022] Chrysin (2.54g; 0.01mol) and anhydrous potassium carbonate (1.66g; 0.011mol) were added to 100ml of stirred acetone, then ethyl bromoacetate (1.84g, 0.011mol) was added to the solution, and the reaction was Heating to reflux was carried out under the condition of heating (50~60° C.) while stirring, and the reaction time was 6 hours. After the reaction was over, it was cooled. The solution was suction-filtered, and the filtrate was concentrated to 40% of the original volume after suction filtration. The filtrate concentrate was washed with petroleum ether, 1 wt% NaOH solution and water in turn, and then vacuum-dried. The product is a light yellow solid, the product yield is 91%, mp: 242-244°C, 1 H NMR (400MHz, d 6 -DMSO):1.25(t,J=6.9Hz,3H);4.19(m,2H);4.96(S,2H...
Embodiment 2
[0030] 5-Hydroxy-7-(2-oxo-2-piperazinylethoxy)-2-phenyl-4H-benzopyrone
[0031]
[0032] A mixture of dicyclohexylcarbodiimide (DCC, 0.75g; 3.372mmol) and 20ml of anhydrous dichloromethane was dripped into 40ml of anhydrous dichloromethane obtained in step (2) of Example 1 (0.96g; 3.06mmol). In the methyl chloride solution, the whole process was carried out in an ice bath, and after the dropwise addition was completed, the reaction was carried out in an ice bath for 12 hours. Remove the ice bath, add the compound piperazine 3.373mmol and triethylamine TEA (0.341g; 3.372mmol), stir at room temperature for 12 hours, filter with suction, concentrate the filtrate to dryness, then add 80ml of ethyl acetate, and filter with suction , the filtrate was washed 3 times with dilute potassium carbonate solution (concentration 1wt%) and saturated NaCl solution respectively, and the organic phase was washed 3 times with dilute HCl (0.30~0.40wt%), and the aqueous phase was combined, and t...
Embodiment 3
[0034] 2-(5-Hydroxy-4-oxo-2-phenyl-4H-benzopyrone-7-oxyl)-N-(2-piperidinylethyl)acetamide
[0035]
[0036] A mixture of dicyclohexylcarbodiimide (DCC, 0.75g; 3.372mmol) and 20ml of anhydrous dichloromethane was dripped into 40ml of anhydrous dichloromethane obtained in step (2) of Example 1 (0.96g; 3.06mmol). In the methyl chloride solution, the whole process was carried out in an ice bath, and after the dropwise addition was completed, the reaction was carried out in an ice bath for 12 hours. Remove the ice bath, add compound 1-(2-aminoethyl)piperidine 3.373mmol and triethylamine TEA (0.341g; 3.372mmol), stir at room temperature for 12 hours, filter with suction, and concentrate the filtrate to dryness. Then add 100ml of ethyl acetate, filter with suction, wash the filtrate with dilute potassium carbonate solution (concentration 1wt%) and saturated NaCl solution 3 times respectively, wash the organic phase with dilute HCl (0.30~0.40wt%) 3 times, and combine the water phas...
