Ethyl P-methyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate (1 g) in 20 ml of 6N hydrochloric acid is heated under reflux overnight. The solution is then poured into water and extracted with methylene chloride. The combined solvent extracts are dried over magnesium sulfate and the solvent is then evaporated off to give P-methyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinic acid.
