In a manner similar to the preparation of N2,N4-bis(3-hydroxyphenyl)-5-fluoro-2,4-pyrimidinediamine, with the addition of triethylamine, 2,4-dichloro-6-ethoxycarbonyl-5-nitropyrimidine and glycine ethyl ester hydrochloride were reacted to yield N2,N4-bis(ethoxycarbonylmethyl)-6-ethoxycarbonyl-5-nitro-2,4-pyrimidinediamine. 1H NMR (CDCl3): mixture of rotamers 8 8.99 and 8.80 (2bs, 1H), 6.22 and 6.00 (2bs, 1H), 4.45 (t, 2H, J=7.2 Hz), 4.31-4.21 (m, 6H), 4.14 (d, 2H, J=5.1 Hz), 1.39 (t, 3H, J=7.2 Hz), 1.34-1.28 (m, 6H); LCMS: ret. time: 26.06 min.; purity: 99%; MS (m/e): 400 (MH+).
