General procedure: The substituted 1-naphthylamine (10 mmol), 2-picolinic acid (12.5 mmol) and Et3N (20 mmol,2.8 mL) were dissolved in DCM (40 mL) followed by dropwise addition of POCl3 (1.88 mL) at 0C. The resulting mixture was stirred at 0C for 0.5 h and warmed to room temperature for 2 h. Then the reaction mixture was cooled to 0C. Ice water was added slowly to quench the reaction. The organic layer was collected, and the aqueous phase was extracted with DCM. The combined organic phase was washed by saturated NaHCO3 and dried over MgSO4. The solvent was evaporated under reduced pressure, and the residue was recrystallized from i-propyl alcohol to give desired product.
According to the analysis of related databases, 4766-33-0, the application of this compound in the production field has become more and more popular.
