YieldReaction ConditionsOperation in experiment
51% With copper; toluene-4-sulfonic acid; In dichloromethane; at 50℃; for 10h;Inert atmosphere; Example 13: Under nitrogen protection, Cu powder (2.5 mmol) was sequentially added to a 10 ml reaction tube containing a magnet.5-bromo-1-methylindoline-2,3-dione (1.75 mmol), bromodifluoromethyl-1,3-benzoxazole (1.75 mmol),p-Toluenesulfonic acid (0.53 mmol), 3.0 ml of dry CH2Cl2 was added, and the reaction was carried out at 50 C for 10 hours.After the reaction was stopped, the solid in the reaction mixture was filtered through a short silica gel column, and the filtrate was extracted with saturated brine and ethyl acetate.The organic layer was taken and dried over anhydrous sodium sulfate.Filter and concentrate. The crude product was separated and purified by column chromatography to give the desired product 3e, yield 51%.
