Procedure
A 250 mL round bottomed flask equipped with stirbar and nitrogen inlet was charged with 3-[3-bromo-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]-4-fluorobenzoic acid (3.65 g, 7.8 mmol), 4-methylmorpholine (2.6 mL, 23.4 mmol), 2-chloro-4,6-dimethoxy-1,3,5-triazine (1.64 g, 9.36 mmol) and tetrahydrofuran (40 mL). After stirring the mixture for 30 min at 250 C, NH4OH (20.0 mL) was added. The mixture was stirred for 30 min and diluted with water. The product precipitated from solution. The precipitated was filtered and washed with water and diethyl ether to give the title compound (2.37 g, 65%) as a white solid. 1H NMR (400 MHz, (CD3)2SO) δ 7.9 (d, J=7.3 Hz, 1H), 7.61 (q, J=8.6 and 6.7 Hz, 1H), 7.5 (m, 2H), 7.3 (t, J=9.6 Hz, 1H), 7.15 (t, J=8.7 Hz, 1H), 6.7 (s, 1H), 5.36 (s, 2H), 2 (s, 3H) ppm. ES-HRMS m/z 469.0172 (M+H calcd for C20H15BrF3N2O3 requires 469.0195).
