Procedure

The title compound was prepared by a procedure similar to the one described for (±) 3-[5-chloro-4-[(2,4-difluorobenzyl)oxy]-2-methyl-6-oxopyrimidin-1(6H)-yl]-N-(2-hydroxyethyl)-4-methylbenzamide using (R)-(−)-1-amino-2-propanol (0.98 mL, 12.45 mmol) as the amine. After reverse phase HPLC purification, the organic extracts were concentrated under reduced pressure and dried in vacuo to afford the desired product (2.70 g, 58%) as beige solid. 1H-NMR (CD3OD, 400 MHz) δ 7.93 (dd, 1H, J=1.6 Hz), 7.69 (d, 1H, J=1.6 Hz), 7.62 (m, 1H), 7.56 (d, 1H, J=8 Hz), 7.01 (m, 2H), 5.59 (q, 2H, J=12.4 Hz), 3.94 (m, 1H), 3.39 (m, 2H), 2.18 (s, 3H), 2.13 (s, 3H), 1.9 (d, 3H, J=6.4 Hz); ES-HRMS m/z 478.1322 (M+H C23H23ClF2N3O4 requires 478.1340). Both (+) and (−) atropomers will be resolved and characterized.
