Reaction Steps

[2-[2-(1-Tridecynyl)phenyl]ethenylidene]bisphosphonic acid (0.101 g, 0.228 mmol) prepared according to Example 10 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 20 minutes, the solvent was removed under reduced pressure to give a yellowish solid. This solid was pulverized and washed successively with dry ether, tetrahydrofuran, acetone, acetonitrile, and ethanol, then dried on the vacuum line, 0.104 g, 0.214 mmol, 94% yield. 1H NMR (D2O) ∂ 0.74 (m, 3H), 1.17 (m, 14H), 1.35 (m, 2H), 1.52 (m, 2H), 2.39 (t, J=7.1 H, 2H), 7.24 (m, 2H), 7.37 (m, 1H), 7.92 (dd+m, J=43.8, 27.0 Hz, 2H); FAB mass spectrum m/z 443 (M-2Na+3H)+, 465 (M-Na+2H)+, 487 (M+H)+.
