Procedimiento

Bromotrimethylsilane (6.0 mL, 45.4 mmol) was added dropwise to (4-fluoro-benzyl)-phosphonic acid dimethyl ester (4.57 g, 20.95 mmol) and stirred in a reaction flask chilled to 0° C. The resulting solution was allowed to warm to ambient temperature and stirred for an additional hour, then concentrated by rotary evaporation to remove volatiles yielding crude (4-fluoro-benzyl) phosphonic acid bis(trimethylsilyl) ester which was used without further purification.
