Procedure

In a manner similar to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine, 2-chloro-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-4-pyrimidineamine and 2-methoxycarbonyl-5-aminobenzofuran were reacted to yield N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-[2-(methoxycarbonyl)benzofuran-5-yl]-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 9.68 (bs, 1H), 8.13-8.10 (m, 2H), 7.63-7.54 (m, 3H), 7.27 (bs, 1H), 7.10 (d, 1H, J=8.7 Hz), 6.80 (d, 1H, J=8.1 Hz), 4.21 (s, 4H), 3.88 (s, 3H); LCMS: ret. time: 23.22 min.; purity: 95%; MS (m/e): 437 (MH+).
