실험 절차

To a suspension of 4-ethyl benzoic acid (4.53 g, 30.16 mmol) in concentrated sulfuric acid (24 mL) at 0° C. was added nitric acid (12 mL). The mixture was stirred for 1.5 h at 0° C. Poured into ice water, filtered and dried the solid to give 5.79 g of the title compound (98%). 1H NMR (400 MHz, DMSO-d6): δ 1.23 (3H, t, J=7.2 Hz), 2.88 (2H, q, J=7.2 Hz), 7.67 (1H, d, J=8.0 Hz), 8.15 (1H, dd, J=1.6, 8.0 Hz), 8.36 (1H, d, J=1.6 Hz).
