Procedure

To a solution of N-(4-((dimethylamino)methyl)-3-(trifluoromethyl)phenyl)-2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetamide (5.8 g, 7.30 mmol) in DCM (50 mL) was added HCl (1,4-dioxane, 5 mL, 20.00 mmol) at rt. The solution was stirred at 20° C. for 30 min. The solution was concentrated in vacuo to give the crude product. The crude material was purified by preparative HPLC (MeCN/H2O as eluants, acidic condition) to yield a off white solid of N-(4-((dimethylamino)methyl)-3-(trifluoromethyl)phenyl)-2-(4-(5-ethoxy-6-oxo-1,6-dihydropyridin-3-yl)-2-fluorophenyl)acetamide, hydrochloride (1.5 g, 2.78 mmol, 38.1% yield). TLC (DCM/MeOH=5:1, Rf=0.3): 1H NMR (400 MHz, CD3OD) δ 8.21 (d, J=1.4 Hz, 1H), 8.04 (d, J=8.4 Hz, 1H), 7.75 (d, J=8.4 Hz, 1H), 7.36-7.53 (m, 5H), 4.50 (s, 2H), 4.20 (q, J=7.0 Hz, 2H), 3.87 (s, 2H), 2.95 (s, 6H), 1.50 (t, J=7.0 Hz, 3H); ES-LCMS m/z 492.2 (M+H).
