実験手順

Next, thioxanthen-9-one-2-carboxylic acid was prepared. A mixture of 2,4′-thiobis(benzoic acid) (50 g, 182 mmol) and methansulfonic acid (600 mL) was heated at 85° C. for 5 h and then cooled to ambient. The reaction mixture was poured onto ice, and the resulting precipitate was collected, washed with water, and dried.
