Reaction Steps
A solution of 5-fluoro-2-aminobenzenethiol (0.94 g, 6.6 mmol) in diethyl oxalate (1.8 mL, 13 mmol) is heated at reflux for overnight. The solution is poured into a mixture of water (9.8 mL), conc. HCl (3.3 mL), and EtOH (4.6 mL). The material is extracted with CHCl3 (3×100 mL). The combined organic extracts are dried over MgSO4, filtered and concentrated to yield an oil. The material is purified by chromatography (25% hexanes/75% CHCl3) to afford a solid that is recrystallized from petroleum ether (0.16 g, 11%). MS for C10H8NO2SF: m/z 226 (M+H)+.
