실험 절차
Add 1,1′-carbonyldiimidazole (2.3 g, 14.2 mmol) to a solution of 2-(benzofur-4-yl)acetic acid (2.5 g, 14.2 mmol) in anhydrous tetrahydrofuran (12 mL) under nitrogen and stir at 20° C. for 4 hours. Bubble anhydrous ammonia through the solution, dilute with anhydrous tetrahydrofuran (10 mL) and stir at 20° C. for 18 hours. Concentrate under reduced pressure, wash the solid with aqueous sodium hydrogen sulfate, distilled water, and dry under vacuum to obtain the title compound as a pale yellow solid.
