반응 단계
A sealed tube was charged with 4-aminonicotinic acid 45 (8.00 g, 57.9 mmol), acetic acid (75 mL) and water (75 mL). The reaction was heated at 75° C. and stirred vigorously until homogeneous. After cooling to 50° C., bromine (10.0 mL, 195 mmol) was added and stirring continued for 16 h. Upon cooling to 0° C., the resulting orange precipitate was collected by filtration, rinsed with H2O, and dried under vacuum to give 46 (10.5 g, 84% yield).
