Procedure

3.4 g (8.5 mmol) of dimethyl (R)-N-(7-nitro-2,3-dimethoxyquinoxalin-5-ylmethyl)-α-aminoethylphosphonate, 8.9 ml (7.5 eq.) of ethyl iodide and 20.9 ml (14.5 eq.) of Hunig's base are mixed in 18 ml of acetonitrile and stirred at 55° C. for 18 hours. The reaction mixture is evaporated and slurried with ethyl acetate. The deposited solid is filtered off and washed with ethyl acetate. The title compound is obtained in the form of a yellow resin after evaporation of the filtrate and column chromatography using ethyl acetate/methanol (95:5) as eluent.
