87% | In 1,4-dioxane; at 100℃; for 10h; | Add 10 mL of 1,4-dioxane as a solvent to a 25 mL round bottom flask. Then add benzoyl formaldehyde hydrate, 4-hydroxycoumarin, and 2- (tetrahydropyrimidine-2 (1H) -subunit) -1- (p-tolyl) ethyl-1-one, Where the molar ratio of benzoyl formaldehyde hydrate, <strong>[4139-61-1]6-bromo-4-hydroxycoumarin</strong> and 2- (tetrahydropyrimidine-2 (1H) -subunit) -1- (p-tolyl) ethyl-1-one Is 1: 1: 1, The ratio of the molar amount of the benzoyl formaldehyde derivative (benzoyl formaldehyde hydrate) to the volume of the solvent mol: L is 1:10; Stir the reaction at a temperature of 100 C. Use TLC to detect the reaction to 10h, The reaction liquid was completely obtained from the reaction of the raw materials. The reaction liquid was cooled to room temperature, and purified by column chromatography to obtain a chromone-substituted 2-hydroxypyrrole derivative ((E) -6-bromo-3- (6-hydroxy- 8- (4-methylbenzoyl) -6-phenyl-1,2,3,4-tetrahydropyrrolo [1,2-a] pyrimidine-7 (6H) -subunit) chroman-2 , 4-dione); wherein the column chromatography eluent is a mixed solvent of ethyl acetate / petroleum ether, and the volume ratio of ethyl acetate to petroleum ether is 2: 1; |
