Reaction Steps
5-Chloro-2-hydroxy-1-[(methylsulfinyl)acetyl]benzene (6.0 g) and trifluoroacetic acid (6 g) are refluxed in benzene (50 ml) for one hour under nitrogen. The solvent is removed under reduced pressure to give a yellow oil, which crystallizes on standing. Recrystallization from ethanol gives white crystals. (3.0 g 54%) m.p. 76°-78° C.
