A mixture of 2-amino-benzenethiol (1.34 mL, 12.5 mmol), 2-bromo-terephthalic acid (1.54 g, 6.3 mmol), cuprous oxide (0.50 g, 3.5 mmol), quinoline (6.3 mL), and pyridine (0.63 mL) was heated in a 180° C. oil bath under nitrogen for 20 hours, then cooled to room temperature. Concentrated hydrochloric acid (20 mL) was added slowly while cooling in cold water, with stirring. The resulting precipitate was filtered, washed with water, and dried to give crude title compound (2 g). LC-MS: m/z 270 (M−1).
