Reaction Steps

1,1-Dimethylethyl (2S)-2-[1-({3-[(2-fluoro-4-iodophenyl)amino]-1-oxidopyridin-4-yl}carbonyl)-3-hydroxyazetidin-3-yl]piperidine-1-carboxylate (57 mg, 0.093 mmol) was dissolved in methanol (2 mL) and treated with 4N hydrochloric acid in dioxane (0.25 mL, 1 mmol) at 50° C. for 2.25 hours. The mixture was concentrated in vacuo and was purified by reverse-phase HPLC followed by lyophilization of the pure fractions to afford 1-({3-[(2-fluoro-4-iodophenyl)amino]-1-oxidopyridin-4-yl}carbonyl)-3-[(2S)-piperidin-2-yl]azetidin-3-ol acetate (35 mg, 0.061 mmol, 66% yield): 1H NMR (400 MHz, d6-DMSO): 7.83 (s, 1H), 7.72 (dt, 2H), 7.55-7.51 (m, 1H), 7.47-7.41 (m, 1H), 7.24 (t, 1H), 4.45-4.32 (m, 1H), 4.14-3.95 (m, 2H), 3.72 (d, 1H), 2.97 (d, 1H), 2.58-2.43 (m, 2H), 1.80-1.73 (m, 1H), 1.67-1.55 (m, 1H), 1.49 (br d, 1H), 1.38-1.16 (m, 2H), 1.16-1.01 (m, 1H); MS (EI) for C20H22FIN4O3: 513 (MH+).
