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-(6-chloropyridin-3-yl)-5-fluoro-4-pyrimidineamine gave N4-(6-chloropyridin-3-yl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 10.10 (bs, 1H), 9.64 (bs, 1H), 8.85 (m, 1H), 8.30 (m, 2H), 8.22 (d, 1H, J=4.2 Hz), 7.43 (d, 1H, J=8.7 Hz), 7.01 (m, 3H), 6.42 (bd, 1H, J=8.4 Hz); LCMS: purity: 93%; MS (m/e): 332 (MH+).
