実験手順
A solution of N-(3,4-dichlorophenyl)-2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetamide (60 mg, 0.108 mmol) in HCl(MeOH, 27.0 μl, 0.108 mmol) was stirred at 20° C. for 1 h. After LCMS analysis showed the starting material had disappeared, the solvent was removed in vacuo. The crude product was purified by preparative HPLC to give pure product N-(3,4-dichlorophenyl)-2-(4-(5-ethoxy-6-oxo-1,6-dihydropyridin-3-yl)-2-fluorophenyl)acetamide (14.72 mg, 0.034 mmol, 31.3% yield): 1H NMR: (400 MHz, CD3OD) δ 7.92 (s, 1H), 7.45 (s, 2H), 7.41 (d, J=7.6 Hz, 1H), 7.38-7.32 (m, 3H), 7.28-7.25 (m, 1H), 7.27 (d, J=2.0 Hz, 1H), 4.14 (m, 2H), 3.79 (s, 2H), 1.47 (t, J=7.0 Hz, 3H); ES-LCMS: m/z 435.0 (M+H).
