Reaction Steps

The title compound was prepared by employing a similar procedure as described for (±) 3-[5-bromo-4-[(2,4-difluorobenzyl)oxy]-2-methyl-6-oxopyrimidin-1(6H)-yl]-4-methyl-N-{1-[(methylamino)carbonyl]methyl}benzamide, substituting S-alanineamide hydrochloride for N-methylglycineamide hydrochloride. Yield 45%: 1H NMR (CD3OD/400 MHz) δ 7.96 (m,1H), 7.73 (dd, 1H, J=2.0 Hz), 7.62 (m, 1H), 7.55 (d, 1H, J=8.0 Hz), 7.01 (m, 2H), 5.56 (abq, 2H), 4.55 (abq, 1H), 2.18 (s, 3H), 2.14 (s, 3H), and 1.45 (d, 3H, J=7.2 Hz); ES-HRMS m/z 535.0757 (M+H calcd for C23H22N4O4F2 Br requires 535.0787). 19F NMR (CD3OD/400 MHz) −111.86 (m) and −115.90 (m).
