Reaction Steps

[2-[3-(1-Tridecynyl)phenyl]ethenylidene]bisphosphonic acid (0.103 g, 0.223 mmol) prepared according to Example 2 was dissolved in dry tetrahydrofuran (10 ml) and stirred while sodium ethoxide in ethanol (0.177M, 2.58 ml, 0.457 mmol) was added. After one hour, the solvent was removed under reduced pressure leaving a brownish yellow solid. This solid was powdered and washed successively with anhydrous ether, tetrahydrofuran, acetonitrile, and ethanol leaving a white solid, 43.3 mg, 0.089 mmol, 38% yield; 1H NMR (D2O, relative to HOD peak at 4.64) ∂0.76 (t, J=6.9 Hz, 3H), 1.05 to 1.58 (several m, 18H), 2.35 (t, J=7.0 Hz, 2H), 7.30 (m, 2H), 7.55 (dd, J=43.8, 27.0 Hz, 1H), 7.69 (m, 2H); FAB mass spectrum m/z 443 (M-2Na+3H)+, 465 (M-Na+2H)+, 487 (M+H)+.
