Reaction Steps

In like manner to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-[3-[2-(N-morpholino)ethyleneoxy]phenyl]-2,4-pyrimidinediamine, N4-(3-tert-butylphenyl)-5-fluoro-N2-(2-methoxycarbonylbenzofur-5-yl)-2,4-pyrimidinediamine reacted with DIBALH to give N4-(3-tert-butylphenyl)-5-fluoro-N2-[2-(hydroxymethylene)benzofur-5-yl]-2,4-pyrimidinediamine. LCMS: retn, time: 23.15 min.; purity: 99%; MS (m/e): 407 (MH+); 1 (DMSO-d6): δ 9.34 (1H, s), 9.22 (1H, s), 8.18 (1H, d, J=3.9 Hz), 8.04 (1H, s), 8.00 (1H, d, J=8.7 Hz), 7.60 (1H, t, J=2.1 Hz), 7.47 (2H, m), 7.34 (1H, t, J=7.8 Hz), 7.21 (1H, d, J=8.7 Hz), 6.69 (1H, s), 5.54 (1H, t, J=5.8 Hz), 4.63 (2H, d, J=5.8 Hz), 1.35 (9H, s).
