Reaction Steps

In like manner to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hyroxyphenyl)-2,4-pyrimidinediamine, N4-(3-tert-butylphenyl)-2-chloro-5-fluoro-4-pyrimidineamine and 2-methoxycarbonyl-5-aminobenzofuran were reacted to give N4-(3-tert-butylphenyl)-5-fluoro-N2-(2-methoxycarbonylbenzofur-5-yl)-2,4-pyrimidinediamine. LCMS: retn, time: 26.76 min.; purity: 97%; MS (m/e): 435 (MH+); 1H NMR (DMSO-d6): δ 9.41 (2H, sl), 8.27 (1H, s), 8.21 (1H, d, J=3.9 Hz), 7.98 (1H, m), 7.77-7.60 (3H, m), 7.37 (1H, t, J=8.1 Hz), 7.22 (1H, d, J=8.1 Hz), 3.98 (3H, s), 1.34 (9H, s).
