This compound was synthesized according to (8) with slight modifications. The iminoester prepared from diphenyl [N-(benzyloxycarbonyl)amino](4-cyanophenyl)methane phosphonate (1.5 g, 3.0 mmol) was dissolved in a mixture of methanol (30 ml) and 0.5 M NH3 in 1,4-dioxane (15 ml), the solution stirred at room temperature overnight, solvent was removed and the oily residue dissolved in CHCl3 (30 ml). Diethyl ether (100 ml) was added, the precipitate collected by filtration, washed with diethyl ether (30 ml×5) and dried in vacuo [yield 1.2 g (73%)]. The crude product was judged sufficiently pure for biotinylation. For use in kinetic studies, further purification was carried out by HPLC (100 mg crude 1) yielding 36 mg 1. [tR 31.58 min, purity 99% (A:B 80:20 to 20:80 in 60 min); m/z (ESI) 516 (M+H)+, 1031 (2M+H)+].
