Procedure

A mixture of (3,4-dichloroisothiazol-5-yl)methanol (1.1 g), chloroform (150 mL) and manganese dioxide (4.7 g) was stirred at 40° C. for 20 hours. The mixture was filtered through Celite and the filtrate was concentrated under reduced pressure to afford the title compound as a yellow solid (0.62 g).

Workup

  1. filtrationThe mixture was filtered through Celite
  2. concentrationthe filtrate was concentrated under reduced pressure
