Procedure
A solution of 1 g of methyl P-methyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate in 10 ml of 6N HCl is refluxed for 16 hours. After cooling, the solid product is collected by filtration and dried, yielding P-methyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinic acid.
