Versuchsvorschrift

To a solution of diethyl(12R,16R)-12-amino-16-(dodecanoyloxy)-1,1-difluoro-11,19-dioxo-4,7,18-trioxa-14-thia-10-azatriacontylphosphonate (1 eq) in DCM (0.1 M) was added trimethylsilyl bromide (10 eq). The reaction mixture was then stirred at room temperature overnight and concentrated. The crude mixture was purified by reverse phase high performance liquid chromatography (HPLC) with C4 column eluting with a gradient of 40-100% MeCN/10 mM NH4OAc (95:5) in 10 mM NH4OAc (pH 9) to give (12R,16R)-12-amino-16-(dodecanoyloxy)-1,1-difluoro-11,19-dioxo-4,7,18-trioxa-14-thia-10-azatriacontylphosphonic acid. 1H NMR (CDCl3): δ 8.47 (br s, 1H), 5.10-5.23 (m, 1H), 4.32 (dd, 1H), 4.18-4.26 (m, 1H), 4.12 (dd, 1H), 3.68-3.86 (m, 2H), 3.44-3.68 (m, 6H), 3.20-3.36 (m, 1H), 2.96-3.16 (m, 2H), 2.76-2.85 (m, 1H), 2.68-2.76 (m, 1H), 2.21-2.38 (m, 4H), 2.12-2.07 (m, 2H), 1.52-1.65 (m, 4H), 1.36-1.15 (m, 32H), 0.87 (t, 6H). LRMS [M+H]=805.5.
