実験手順

To a solution of ethyl 2-[P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinyloxyimino]propionate (500 mg) in tetrahydrofuran (10 ml) is added hydrazine (1 eq.) and 5% rhodium on activated charcoal (50 mg) at 15°-25°, with stirring for 2 hours. The reaction is then filtered and the filtrate is diluted with methylene chloride, washed, dried and concentrated to dryness to give ethyl 2-[P-ethyl-2-hydroxyamino-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinyloxyimino]propionate.
