실험 절차

To a solution of diethyl 2-(5-amino-2-(4-methoxy-2-methylphenethyl)benzo[f][1,7]naphthyridin-8-yl)-1,1-difluoro-2-oxoethylphosphonate (2-4) (1.0 equiv.) in DCM (0.05 M) at 0° C. was added TMSI (5.0 equiv.). The reaction was warmed to room temperature over 2 hours, and more TMSI was added (2.5 equiv.). The reaction was stirred for another 30 minutes, and then quenched with small amounts of water. The DCM was removed by evaporation, and then added DMSO/water. The mixture was adjusted to pH 9 and directly purified on RP-HPLC using a C18 column, eluting with 10-40% 95:5 (MeCN/5 mM NH4OAc) in 10 mM NH4OAc (pH 9) gradient. The fractions containing the product were combined and concentrated in vacuo to give 2-(5-amino-2-(4-methoxy-2-methylphenethyl)benzo[f][1,7]naphthyridin-8-yl)-1,1-difluoro-2-oxoethylphosphonic acid (9) as a solid. 1H NMR (Dimethylsulfoxide-d6): δ 8.82 (s, 1H), 8.5 (br, 1H), 8.44 (s, 1H), 8.2 (br, 1H), 7.98 (d, 1H, J=8.2 Hz), 7.2 (br, 2H), 7.05 (d, 1H, J=8.3 Hz), 6.73 (s, 1H), 6.67 (d, 1H, J=8.3 Hz), 3.70 (s, 3H), 2.99-2.87 (m, 4H), 2.25 (s, 3H). LRMS [M+H]=502.2
