Reaction Steps

In like manner to the preparation of 5-fluoro-N4-(3-hydroxyphenyl)-N2-[4-(3-phenyl-1,2,4-oxadiazol-5-yl)methyleneoxyphenyl]-2,4-pyrimidinediamine, 2-chloro-N4-[3-[[4-(ethoxycarbonyl)piperidino]carbonyl]phenyl]-5-fluoro-4-pyrimidineamine and 3-hydroxyaniline were reacted to provide N4-[3-[[4-(ethoxycarbonyl)piperidino]carbonyl]phenyl]-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine. 1H NMR (CD3OD): δ 7.93 (d, 1H, J=3.6 Hz), 7.89 (t, 1H, J=1.8 Hz), 7.83 (td, 1H, J=1.2 and 8.4 Hz), 7.41 (t, 1H, J=7.8 Hz), 7.11-6.95 (m, 4H), 6.41 (td, 1H, J=1.8 and 7.2 Hz), 4.44 (bd, 1H, J=12.9 Hz), 4.10 (q, 2H, J=7.2 Hz), 3.73 (bd, 1H, J=12.3 Hz), 3.18-2.98 (m, 2H), 2.67-2.55 (m, 1H), 2.05-1.53 (m, 4H), 1.23 (t, 3H, J=7.2 Hz); 19F NMR (282 MHz, CD3OD): −47483; LCMS: purity: 99%; MS (m/e): 480 (MH+).
