Participants

Reaction Steps

In like manner to the preparation of N4-(3-chloro-4-trifluoromethoxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidineamine, the reaction of 3-hydroxyaniline with 2-chloro-N4-(5-chloropyridin-2-yl)-5-fluoro-4-pyrimidineamine gave N4-(5-chloropyridin-2-yl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 10.80 (bs, 1H), 9.77 (bs, 1H), 8.45 (bd, 1H), 8.26 (d, 1H, J=3.9 Hz), 8.15 (d, 1H, J=8.7 Hz), 7.85 (dd, 1H, J=2.4 and 8.7 Hz), 7.06 (m, 3H), 6.43 (bd, 1H, J=7.2 Hz); LCMS: purity: 97%; MS (m/e): 332 (MH+).
