A stirred suspension of 2-(((pentafluorophenyl)thio)methyl)pyridine, hydrochloride (2.0 g) in methylene chloride (50 ml) at 0° C. was treated portionwise with m-chloroperoxybenzoic acid (1.41 g) over 1/2 hour. The mixture was allowed to warm to ambient temperature, sufficient methylene chloride was added to form a solution, and the mixture was stirred a further 1/2 hour. The solution was washed with saturated Na2CO3 solution and water, dried (MgSO4) and evaporated. The residue was converted into the hydrochloride in acetone with ethereal HCl solution to give the title compound, hydrochloride (1.3 g) mp 154°-6° C. (Found: C,41.6; H,2.15; N,3.8 C12H6F5NOS.HCl requires C41.9; H,2.05; N,4.1%).
