Reaction Steps

The title compound was prepared by a procedure similar to the one described for 3-[5-bromo-4-[(2,4-difluorobenzyl)oxy]-6-oxopyrimidin-1(6H)-yl]-4-methyl-N-{1-[(methylamino)carbonyl]methyl}benzamide using ethanolamine (0.16 mL 2.5 mmol) as the amine and without the addition of a second equivalent of N-methylmorpholine. After reverse phase HPLC purification, the organic extracts were concentrated under reduced pressure and dried in vacuo to afford the desired product (551.7 mg, 63%) as white solid. 1H-NMR (CD3OD, 400 MHz) δ 8.32 (s, 1H), 7.92 (dd, 1H, J=2 Hz), 7.77 (d, 1H, J=2 Hz), 7.62 (m, 1H), 7.53 (d, 1H, J=8 Hz), 7.01 (m, 2H), 5.60 (q, 2H, J=12.4 Hz), 3.68 (t, 2H), 3.48 (t, 2H), 2.19 (s, 3H) ; ES-HRMS m/z 494.0518 (M+H C21H19BrF2N3O4 requires 494.0522).
