Participants

Reaction Steps

To a solution of diethylphosphite (0.22 mL) in toluene (5 mL) at 0° C. was added NaH (60% in mineral oil, 20 mg). The reaction mixture was stirred for 1 hour and then a solution of diethyl [3-bromo-7-(bromomethyl)-2-naphthyl](difluoro)methylphosphonate (220 mg) in toluene (2 mL) was added dropwise. The reaction was stirred for 1 h at 0° C., quenched with a solution of saturated NH4Cl, extracted with EtOAc and dried over Na2SO4. The organic extracts were evaporated to dryness and the residue was purified by flash chromatography eluting with 50% EtOAc/hexanes to afford the titled compound.
