الإجراء التجريبي

In a manner similar to the preparation of 2-chloro-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-4-pyrimidineamine, 2,4-dichloro-5-fluoropyrimidine and 6-amino-2H-pyrido[3,2-b]-1,4-oxazin-3(4H)-one were reacted to yield 2-chloro-5-fluoro-N4-[2H-pyrido[3,2-b]-1,4-oxazin-3(4H)-one-6-yl]-4-pyrimidineamine. 1H NMR (DMSO-d6): δ 4.63 (s, 2H), 7.34 (d, J=8.7 Hz, 1H), 7.44 (d, J=8.4 Hz, 1H), 8.33 (d, J=3.3 Hz, 1H), 10.14 (s, 1H, NH), 11.19 (s, 1H, NH); 19F NMR (282 MHz, DMSO-d6): δ −152.35; LCMS: ret. time: 26.74 min.; purity: 85.90%; MS (m/e): 296.13 (MH+).
