Procedure

A suspension of N-(4-(2-(benzyloxy)ethoxy)-3-(trifluoromethyl)phenyl)-2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetamide (50 mg, 0.071 mmol) in MeOH (10 mL) was added to a solution of Pd/C (15.10 mg, 0.142 mmol) in MeOH (10 mL). The mixture was hydrogenated under a H2 atmosphere at 26° C. for 2 h. Then the solution was filtered and concentrated. The crude material was purified by preparative HPLC (MeCN/H2O as eluants, basic condition) to yield a white solid of 2-(4-(5-ethoxy-6-oxo-1,6-dihydropyridin-3-yl)-2-fluorophenyl)-N-(4-(2-hydroxyethoxy)-3-(trifluoromethyl)phenyl)acetamide (26.17 mg, 0.053 mmol, 74.6% yield). TLC (DCM/MeOH=10/1, Rf=0.4): 1H NMR (400 MHz, CD3OD) δ 7.84-7.83 (m, 1H), 7.72-7.70 (d, J=8.8 Hz, 1H), 7.43-7.41 (m, 1H), 7.39-7.29 (m, 3H), 7.23-7.22 (d, J=2.0 Hz, 1H), 7.17-7.15 (d, J=9.2 Hz, 1H), 4.14-4.11 (m, 4H), 3.88-3.86 (m, 2H), 3.76 (s, 2H), 1.47-1.44 (t, J=7.0 Hz, 3H); ES-LCMS m/z 495.0 (M+H).
