実験手順
A solution of 4.97 g of (5-trifluoromethyl-2-pyridyloxy)-3,4-dinitrobenzene in 15 ml of toluene is refluxed, and 3.21 g of melted P,P-dimethyl-aminomethylphosphine oxide are added dropwise. The mixture is refluxed for a further 2 hours, nitrous gases being evolved at the start. The brown solution is subsequently concentrated by evaporation, and the residue is recrystallised from 50 ml of ethyl acetate to thus obtain 4.10 g (70% of theory) of N-[2-nitro-5-(5-trifluoromethyl-2-pyridyloxy)-phenyl]-P,P-dimethyl-aminomethylphosphine oxide in the form of yellow crystals, m.p. 158°-160° C.
