Procedure

A mixture of methyl 3-[5-chloro-4-[(2,4-difluorobenzyl)oxy]-2-(methylsulfonyl)-6-oxopyrimidin-1(6H)-yl]-4-methylbenzoate (from Step 1) (3.02 g, 6.05 mmol), allyl amine (0.55 mL, 7.26 mmol), and DMAP (0.07 g, 0.61 mmol) in dioxane (8 mL) was stirred at ambient temperature overnight. Observed product and impurity (1:1 ratio). Added ethyl acetate (4 mL), cooled (0° C.) the reaction mixture, filtered the precipitate, and dried in vacuo to give the product as a white solid (1.17 g, 41%). 1H NMR (CD3OD/400 MHz) δ8.08 (m, 1H) , 7.82 (s, 1H), 7.57 (m, 2H), 7.00 (t, 2H, J=8.8 Hz), 5.80 (m, 1H), 5.51 (m, 2H), 5.07 (m, 2H), 4.56 (s, 1H), 3.93 (m, 1H), 3.89 (s, 3H), 3.65 (s, 3H). ESHRMS m/z 476.1184 (M+H calculated for C23H21ClF2N3O4 requires 476.1183).
