Reaction Steps
A mixture of methyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate (4.7 mmol) and phosphorus pentasulfide (1.2 mmol) is heated to 150°-160° under nitrogen for 3-4 hours. After cooling, the residue is purified by preparative thin-layer chromatography (on silica gel, eluting with 20% ethyl acetate/hexane) to give O-methyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinothioate.
