Procedure

2-Buthylthiocyclopentanone (88 g) was reacted with a 30% excess solution of mono-perphthalic acid in ether at 0° C. After the reaction was completed, the excess mono-perphthalic acid was treated with sodium sulfite, and the resultant solution was washed, evaporated to remove the solvent, and then distilled, thereby giving 2-butylsulfonylcyclopentanone (78 g).
