Procedure

Methyl 3-[5-bromo-4-[(2,4-difluorobenzyl)oxy]-2-(methylsulfonyl)-6-oxopyrimidin-1(6H)-yl]-4-methylbenzoate (from Step 1) (0.35 g, 0.64 mmol), DMAP (0.01 g, 0.06 mmol), and methylamine (0.97 mL of a 2M solution in THF, 1.93 mmol) were combined and stirred at ambient temperature. Reaction complete after 4 h. Washed with 5% citric acid, extracted in DCM, dried over Na2SO4, filtered, concentrated, and dried in vacuo to give a brown film. Dissolved in a small amount of DCM, added hexane, and cooled. Filtered precipitate and washed with a solution of cold 50% DCM/hexane. Dried resulting white solid in vacuo (0.22 g, 69%). 1H NMR (CD3OD/400 MHz) δ8.04 (m, 1H), 7.77 (s, 1H), 7.58 (q, 1H, J=8.8 Hz), 7.53 (d, 1H, J=8.4 Hz), 6.99 (m, 2H), 5.52 (s, 2H), 3.87 (s, 3H), 2.84 (s, 3H), 2.10 (s, 3H). ESHRMS m/z 494.0523 (M+H calculated for C21H19 BrF2N3O4 requires 494.0522).
