Procedure

To a stirred and cooled mixture of N-(2-ethylphenyl)hydrazinecarbothioamide (0.500 g, 2.56 mmol) and acetic acid (2.00 mL, 17.5 mmol) was added sodium nitrite (0.177 g, 2.56 mmol) in water (1 mL). The mixture turned yellow upon addition and the reaction was stirred for 1 hour. The solid was filtered and the title compound was obtained as an orange solid (0.389 g, 73%): 1H NMR (400 MHz, CDCl3) δ 9.02 (s, 1H), 7.42-7.28 (m, 4H), 2.76 (q, J=7.5 Hz, 2H), 1.25 (t, J=7.5 Hz, 3H); 13C NMR (101 MHz, CDCl3) δ 138.69, 137.90, 130.38, 128.28, 128.14, 121.60, 24.73, 14.79; ESIMS m/z 179 ([M+H]-N2+).
