Reaction Steps

In a like manner to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine, 2-chloro-N4-(3-chloro-4-methoxyphenyl)-5-fluoro-4-pyrimidineamine and 5-amino-2-(methoxycarbonyl)benzofuran were reacted to produce N4-(3-chloro-4-methoxyphenyl)-5-fluoro-N2-[2-(methoxycarbonyl)benzofuran-5-yl]-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 9.34 (bs, 2H), 8.10-8.07 (m, 2H), 7.78 (t, 1H, J=2.7 Hz), 7.66-7.53 (m, 4H), 7.12 (d, 1H, J=9.3 Hz), 3.87 (s, 3H), 3.85 (s, 3H); LCMS: purity: 99%; MS (m/e): 443 (MH+).
