Reaction Steps

Finally, propyl thioxanthen-9-one-2-carboxylate (S-20) was prepared. Thioxanthen-9-one-2-carboxylic acid (35 g, 137 mmol) was suspended in a mixture of toluene (250 mL), n-propanol (250 mL), and concentrated sulfuric acid (2 mL) and heated at reflux with stirring for 3 d. The reaction mixture was concentrated, and the resulting solid residue was washed with water and dried. The product was purified by recrystallization from heptane to provide 26.6 g (65% of theory) of a pale yellow solid.
