Procedure
2-Hydroxy-1-[(methylsulfinyl)acetyl] benzene (1.5 g 0.0075m) and trifluoroacetic acid (1.5 g) are refluxed in benzene (25 ml) for one hour under nitrogen. The solvent is removed under reduced pressure to give a pale yellow oil which crystallizes on standing. Recrystallization from ethanol gave white crystals, (0.611 g 45%), m.p. 81°-82° C.
