Procedure

A solution of N-hydroxy-2-[1-(4-phenoxyphenylthio)-cyclopent-1-yl]-acetamide (45 mg) in acetone (4 ml) was treated with sodium periodate (260 mg) in water (2 ml). Over the course of 24 hours, two additional portions of sodium periodate (260 mg) were added. After complete disappearance of starting material the solution was diluted with methylene chloride, filtered, dried, and the solvent evaporated under reduced pressure. Preparative TLC on silica gel and elution with 10% methanol/methylene chloride gave N-hydroxy-2-[1-(4-phenoxyphenylsulfinyl)-cyclopent-1-yl]-acetamide (15 mg), PMR (CDCl3) 7.64 (d,2H), 7.44 (t,2H), 7.30-7.05 (m,5H), 2.97 (d,1H), 2.53 (d,1H), 2.15-1.65 (m,8H).
