Procedure

4-{[3-chloro-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]methyl}benzoic acid (2.00 g, 4.76 mmol) was suspended in N,N-dimethylformamide (10 mL). 1-Hydroxybenzotriazole (0.772 g, 5.71 mmol) was added followed by 4-methylmorpholine (1.57 mL, 14.28 mmol), 1-amino-2-methyl-2-propanol hydrochloride (1.49 g, 11.90 mmol) and then 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (1.28 g, 6.66 mmol). The resulting mixture was stirred at room temperature for 2 days at which time the reaction was diluted with H2O (50 mL). The reaction mixture was then extracted with ethyl acetate. The combined organic extracts were washed with saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated. The resulting solid was washed with diethyl ether to provide the title compound as a tan solid (2.08 g, 89%). 1H NMR (400 MHz, CDCl3) δ 7.72 (d, J=8.2 Hz, 2H), 7.51 (app q, J=7.7 Hz, 1H), 7.25-7.21 (m, 1H), 7.10 (d, J=8.2 Hz, 2H), 6.93 (app dt, J=1.6, 8.3, 9.4 Hz, 1H), 6.87-6.82 (m, 1H), 6.01 (s, 1H), 5.32 (s, 2H), 5.19 (s, 2H), 3.42 (d, J=5.9 Hz, 2H), 2.26 (s, 3H), 1.23 (s, 6H). ES-HRMS m/z 491.1522 (M+H calcd for C25H26ClF2N2O4 requires 491.1544).
