Procedure
4-Ethylphenyl isothiocyanate (3.48 mmol, 1 eq) was added to 2-amino-4-nitrophenol (3.48 mmol, 1 eq) dissolved in 10 mL of methanol, and stirred at room temperature for 24 hours. The organic solvent was removed by evaporation under reduced pressure, and then the precipitate was filtered under reduced pressure with hexane to yield the title compound (a). Yellow-green powder (79%), mp 137-138° C.; 1H NMR (Acetone-d6 400 MHz) δ 9.475 (s, 1H), 9.351 (s, 1H), 8.755 (s, 1H), 7.968 (d, J=9.8 Hz, 1H), 7.464 (d, J=8.0 Hz, 2H), 7.282 (d, J=8.8 Hz, 2H), 7.089 (d, J=9.2 Hz, 1H), 2.658 (q, J=7.6 Hz, 2H), 1.225 (t, J=7.6 Hz, 3H).
