Example 6. Synthesis of N-(6-(morpholinomethyl)pyridin-2-yl)-2-(2- (trifluoromethyl)phenyl)benzo[d]oxazole-7-carboxamide (Compound 125) : Step 1) Preparation of ethyl 6-aminopicolinate (20): 19 20To a solution of 2-amino-6-pyridinecarboxyric acid (19; 6.0 g, 43.5 mmol) in ethanol (150 mL) was added SOCl2 (12.0 g, 101 mmol) at 0 0C. The resulting reaction mixture was stirred under reflux for 12 h. Upon cooling to room temperature, the reaction mixture was concentrated under reduced pressure. Enough saturated aqueous Na2CO3 solution was added to adjust the pH = 9. The mixture was concentrated under reduced pressure and dichloromethane (150 mL) was added to the resulting residue. The mixture was stirred vigorously at room temperature for 30 min and then filtered. The filtrate was concentrated under reduced pressure to afford ethyl 6-aminopicolinate 20 (5.5 g, 76%).
According to the analysis of related databases, 23628-31-1, the application of this compound in the production field has become more and more popular.
