실험 절차

To a stirred solution of 2-Amino-6-naphthoic acid (0.3 g, 1.6 mmol) in DMF (2 mL) and pyridine (0.3 mL) was added at 0° C., acryloyl chloride (0.15 g, 1.6 mmol). The resulting mixture was allowed to come to rt and stirred further for 2 h. After that it was poured in water (5 mL) and the solid separated was filtered and dried under reduced pressure to get the desired product (160 mg, 41.5%) as a pale brown solid. This solid was used in the next step without further purification.
