YieldReaction ConditionsOperation in experiment
45% With pyridine In tetrahydrofuran at 65℃; for 3 h; Inert atmosphere 3. Synthesis of intermediate 107-3 Under a nitrogen atmosphere, the intermediate 107-2 (8.0 g, 54.0 mmol) as a raw material was dissolved in 100 mL of anhydrous tetrahydrofuran at room temperature in a 250 mL single-necked flask, followed by sequentially adding carbonyldiimidazole CDI (19.7 g, 108 mmol) and pyridine (8.54 g, 108 mmol) into the reaction system. Next, the reaction system was heated to 65°C, and then carried out for 3h. After detecting the reaction was completed, the reaction system was cooled to room temperature. The reaction mixture was poured into 100 mL of ice water to quench the reaction. The reaction system was washed with 300 mL of dichloromethane three times, and the organic phases were combined, washed with 300 mL of saturated brine three times, dried over anhydrous sodium sulfate and concentrated to dryness. The resulting residue was purified by silica gel column chromatography (eluent: EA/PE (1:10-1:5)), and the product was collected and concentrated to dryness to give 4.2 g of the intermediate 107-3 (45percent) as a white solid. LCMS: 175.1.
