Reaction Steps

To ethyl P-methyl-α-[2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenoxy]ethylphosphinate (1.1 g) in ethanol (10 ml) is added potassium hydroxide (0.5 g) in water (15 ml). The mixture is stirred at RT for 4 hours. The ethanol is removed, and the aqueous solution is acidified and extracted with ether. The combined extracts are dried and evaporated to dryness to give P-methyl-α-[2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-ethylphosphinic acid.
