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 5-amino-2-methoxycarbonylbenzofuran with 2-chloro-N4-(4-chlorophenyl)-5-fluoro-4-pyrimidineamine gave N4-(4-chlorophenyl)-5-fluoro-N2-(2-methoxycarbonylbenzofuran-5-yl)-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 10.28 (bs, 1H), 10.18 (bs, 1H), 8.25 (d, 1H, J=4.5 Hz), 7.96 (bs, 1H), 7.84 (m, 1H), 7.67 (m, 3H), 7.57 (m, 1H), 7.37 (bd, 2H, J=9.0 Hz), 3.88 (s, 3H); LCMS: purity: 96%; MS (m/e): 413 (MH+).
