Procedure

4-{[3-chloro-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]methyl}benzoic acid (12.0 g, 28.58 mmol) was suspended in tetrahydrofuran (100 mL). 2-Chloro-4,6-dimethoxy-1,3,5-triazine (6.02 g, 34.3 mmol) was added followed by 4-methylmorpholine (9.43 mL, 85.74 mmol). The resulting mixture was stirred at room temperature for 1.5 hours at which time NH4OH (50.0 mL) was added. The resulting mixture was stirred at room temperature for 1 hour and then partially concentrated. The precipitate was collected by filtration washing with H2O and diethyl ether to provide an off-white solid (12.11 g, >100%). 1H NMR (400 MHz, DMSO-d6) δ 7.91 (br s, 1H), 7.80 (d, J=8.3 Hz, 2H), 7.63 (app q, J=7.9 Hz, 1H), 7.31 (dt, J=2.6, 10.5 Hz, 1H), 7.17-7.12 (m, 1H), 7.13 (app d, J=8.3 Hz, 2H), 6.59 (s, 1H), 5.32 (s, 2H), 5.27 (s, 2H), 2.28 (s, 3H). ES-HRMS m/z 419.0968 (M+H calcd for C21H18ClF2N2O3 requires 419.0969).
