Procedure

To a reaction vessel (borosilicate culture tube) was added 4-nitrophenyl 3-{[3-bromo-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]methyl}benzylcarbamate (from step 1) (0.350 g, 0.570 mmol) dissolved in dichloromethane (6.0 mL). The parallel reaction apparatus was then orbitally shaken (Labline Benchtop Orbital Shaker) at approximately 200 RPM at room temperature for 15 minutes. A stock solution of N,N-dimethylamine in tetrahydrorfuran (0.427 mL, 2.0 M) was then added to the reaction vessel and the reaction apparatus was orbitally shaken at room temperature overnight. The reaction mixture was concentrated and subjected to chromatography (silica gel, ethyl acetate with 10% methanol/hexanes) which afforded an off white solid (0.226 g, 63.3%). 1H NMR (400 MHz, DMF-d6) δ 7.81 (app q, J=7.92 Hz, 1H), 7.40-7.19 (m, 5H), 7.06 (d, J=7.45 Hz, 1H), 6.88 (app t, J=5.84 Hz, 1H), 6.68 (s, 1H), 5.45 (s, 2H), 5.42 (s, 1H), 4.35 (d, J=5.84 Hz, 1H), 2.92 (s, 6H), 2.44 (s, 3H). ES-HRMS m/z 520.1065 (M+H C24H24BrF2N3O3 requires 520.1042).
