HCID 220603265-fluoro-N2-(2-methoxycarbonylbenzofuran-5-yl)-N4-(4-isopropoxyphenyl)-2,4-pyrimidinediamine

Procedure

In a manner similar to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine, 2-chloro-5-fluoro-N4-[4-(isopropoxy)phenyl]-4-pyrimidineamine and 2-methoxycarbonyl-5-aminobenzofuran were reacted to yield 5-fluoro-N2-(2-methoxycarbonylbenzofuran-5-yl)-N4-(4-isopropoxyphenyl)-2,4-pyrimidinediamine. 1H NMR (CDCl3): δ 8.04 (d, 1H, J=1.8 Hz), 7.49-7.41 (m, 4H), 7.35 (dd, 1H, J=2.4 and 8.7 Hz), 7.14 (bs, 1H), 6.90 (d, 2H, J=9.3 Hz), 6.70 (bs, 1H), 4.56 (2q, 1H, J=5.7 Hz), 3.98 (s, 3H), 1.37 (d, 6H, J=5.7 Hz); LCMS: ret. time: 25.52 min.; purity: 98%; MS (m/e): 437 (MH+).
