A mixture of methyl P-ethyl-2-nitro-5-(3,5-dichloro-2-pyridyloxy)phenylphosphinate (0.6 g.), methanol (10 ml.) and 5% aqueous potassium hydroxide (10 ml.) is heated to 90° for 15 min. The basic aqueous solution is acidified and extracted with ether. The combined ether extracts are washed and dried and the solvent is evaporated off to give P-ethyl-2-nitro-5-(3,5-dichloro-2-pyridyloxy)phenyl-phosphinic acid.
