A mixture of 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)-N-(3-(2-morpholinoethoxy)-5-(trifluoromethyl)phenyl)acetamide (80 mg, 0.117 mmol) and TFA (10 mL, 10% in DCM) was stirred at 25° C. for 2 h. The mixture was concentrated. To the residue was added NH3 (6 mol/L in MeOH, 1 mL) and concentrated. The residue was purified by preparative TLC (DCM/MeOH=15:1, Rf=0.4) to give an off white solid of 2-(4-(5-ethoxy-6-oxo-1,6-dihydropyridin-3-yl)-2-fluorophenyl)-N-(3-(2-morpholinoethoxy)-5-(trifluoromethyl)phenyl)acetamide (35.72 mg, 0.061 mmol, 51.7% yield): 1H NMR (400 MHz, CD3OD): δ 7.59 (s, 1H), 7.46 (s, 1H), 7.43-7.37 (m, 1H), 7.36-7.30 (m, 2H), 7.29 (d, J=2.0 Hz, 1H), 7.21 (d, J=2.0 Hz, 1H), 6.96 (s, 1H), 4.23 (t, J=5.2 Hz, 2H), 4.11 (q, J=6.8 Hz, 2H), 3.79 (s, 2H), 3.78-3.69 (m, 4H), 3.02-3.00 (m, 2H), 2.80-2.79 (m, 4H), 1.45 (t, J=6.8 Hz, 3H). ES-LCMS m/z: 564 (M+H).
