75% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,4-dioxane; water; at 100℃;Inert atmosphere; | Take compound XIII (1.3g, 5mmol), 2,3-dichlorophenylboronic acid (1.1g, 6mmol), K2CO3 (1.4g, 10mmol), Pd[P(C6H5)3]4 (0.3g, 0.25mmol) In a mixed solution of dioxane (18 mL)/water (2 mL), heat and stir at 100 C. under the protection of nitrogen until TLC indicates that the reaction is complete.After the reaction mixture was cooled to room temperature, it was poured into ice water (20 mL), stirred, and extracted with dichloromethane (20 mL×3). The extracted organic phases were combined, washed with water (50 mL×3), and dried over anhydrous sodium sulfate. The dried organic phase was evaporated on a rotary evaporator to remove the solvent, and the obtained residue was purified by column chromatography to obtain the product XIV-1, 1.2 g, with a yield of 75%. |
