Versuchsvorschrift
A mixture of 3 g of diethyl N-[2-nitro-5-(5-trifluoromethyl-2-pyridyloxy)phenyl]-aminomethylphosphonate and 5 g of trimethylbromosilane is stirred for 18 hours at 20° C. Excess trimethylbromosilane is removed by evaporation and the residue is then taken up in ethanol and the solution is concentrated, affording 2.51 g (96.9% of theory) of the title compound with a melting point of 94° C. (decompos.).
