Participants

Reaction Steps

In like manner to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hyroxyphenyl)-2,4-pyrimidinediamine, 2-chloro-5-fluoro-N4-(3-isopropylphenyl)-4-pyrimidineamine and 2-methoxycarbonyl-5-aminobenzofuran were reacted to give 5-fluoro-N4-(3-isopropylphenyl)-N2-(2-methoxycarbonylbenzofur-5-yl)-2,4-pyrimidinediamine. LCMS: retn, time: 26.05 min.; purity: 99%; MS (m/e): 420 (M+), 422 (MH+); 1H NMR (DMSO-d6): δ 10.00 (1H, s), 9.95 (1H, s), 8.31 (1H, d, J=4.8 Hz), 8.11 (1H, s), 7.74 (3H, m), 7.35 (1H, s), 7.35 (1H, t, J=7.2 Hz), 7.12 (1H, d, J=7.2 Hz), 3.99 (3H, s), 2.83 (1H, sept, J=6.9 Hz), 1.20 (6H, d, J=6.9 Hz).
