Methyl Thioglycolate → 3-(2'-Chloro-4'-trifluoromethylphenoxy)-6-nitrophenyl methoxycarbonylmethyl disulfide

Participants

Reaction Steps

5.3 parts by weight of methyl thioglycolate were added dropwise to a solution of 19.2 parts by weight of 3-(2'-chloro-4'-trifluoromethylphenoxy)-6-nitrobenzenesulfenyl chloride in 100 parts by volume of absolute ether at room temperature, the reaction mixture was stirred for a further two hours and then evaporated to dryness under reduced pressure, and the oily residue was crystallized using diisopropyl ether. 25 parts by weight (90% yield) of 3-(2'-chloro-4'-trifluoromethylphenoxy)-6-nitrophenyl methoxycarbonylmethyl disulfide of melting point 66°-68° C. were obtained (compound No. 3).
