Participants

Reaction Steps

A solution of 7-Chloro-1,4-dihydro-6-fluoro-5-nitroquinoxaline-2,3-dione (0.100 g, 0.385 mmol) and ethanethiol, sodium salt (0.130 g, 1.55 mmol) in DMSO (1.0 mL) was stirred at room temperature for 24 h. The resulting solution was diluted with water (5 mL) and acidified with concd HCl (4-5 drops) to pH ˜5. The precipitated solid was collected by filtration under vacuum, washed with water (10 mL), and dried under vacuum to obtain 0.098 g (84%) pure (HPLC) title compound as a yellow powder; mp darkens at 323° C.; 1H NMR (DMSO-d6) δ 1.04 (t, 3H, J=7.2 Hz), 2.82 (q, 2H, J=7.5 Hz), 7.34 (s, 1H), 12.20 (s, 1H), 12.25 (s, 1H).
