10 ml of N-butyllithium solution (2.1 M solution in hexane) were added dropwise to 50 ml of abs. THF under an argon atmosphere at 0° C. The solution was stirred for 30 minutes at 0° C. and for 15 hours at room temperature, then added to 3.01 ml diethyl chlorophosphonate (20 mmol) at −76° C. and stirred for 1 h at 0° C., then for 16 hours at room temperature. A white solid was filtered off, and the solvent was removed on a rotary evaporator.
