A solution of triethyl 4-phosphonobutyrate (1.00 g, 3.96 mmol) in 1 mL of THF was added to potassium bis(trimethylsilyl)amide (0.5 M in THF, 8.70 ml, 4.36 mmol) at −78° C. After stirring for 1 h at −78° C., 1-iodododecane (1.2 mL, 4.75 mmol) was added dropwise. The reaction was removed from the bath, warmed to rt and stirred for 2 h. The reaction was diluted with ethyl acetate (50 ml), washed with 2 N HCl (50 mL), sat'd NaCl (50 mL), dried and concentrated. Flash chromatography using 3:1 v/v hexane/acetone afforded 610 mg of the title compound: ESI-MS 421.3 (M+H).
