m-Chloroperbenzoic acid → 1-[2-(4-Allyloxy-phenylmethanesulfinyl)-ethyl]-1H-[1,2,3]triazole

Participants

Reaction Steps

A solution of 1.86 g (8.29 mmol) 77% 3-chloroperbenzoic acid in 40 ml ethyl acetate was added at −30° C. within 20 min. to a solution of 1.90 g (6.90 mmol) 1-[2-(4-allyloxy-benzylsulfanyl)-ethyl]-1H-[1,2,3]triazole in 160 ml dichloromethane and stirred for 1 h. The mixture was allowed to warm to r.t. washed with sat. NaHCO3-solution, water and evaporated. The residue purified by chromatography on silica gel (ethyl acetate/methanol 5:1) to give 1.25 g of the title compound as white powder.
