2,4-Dichloro-5-fluoropyrimidine → N4-[3-(N-tert-butoxycarbonyl-N-methylaminomethylene)-phenyl]-2-chloro-5-fluoro-4-pyrimidineamine

Participants

Reaction Steps

In like manner to the preparation of 2-chloro-5-fluoro-N4-(3-methyloxycarbonyl-4-methoxyphenyl)-4-pyrimidineamine, 2,4-dichloro-5-fluoropyrimidine and 3-(N-tert-butoxycarbonyl-N-methylaminomethylene)-aniline were reacted to produce N4-[3-(N-tert-butoxycarbonyl-N-methylaminomethylene)-phenyl]-2-chloro-5-fluoro-4-pyrimidineamine R940315. 1H NMR (DMSO-d6): δ 10.13 (1H, s), 8.42 (1H, d, J=3.6 Hz), 7.69 (1H, m), 7.64 (1H, s), 7.45 (1H, t, J=7.6 Hz), 7.09 (1H, d, J=7.8 Hz), 4.48 (2H, s), 2.90 (3H, s), 1.49 (9H, m); purity 92%; MS (m/e): 367 (MH+).
