Reaction Steps
A mixture of 7-amino-4-methylthiopyrido[4,3-d]pyrimidine (215 mg, 1.12 mmol) and 3-fluoroaniline (1.16 g, 10.4 mmol) is stirred at 160° C. for 30 min. The resulting product is chromatographed over silica gel (6-7% MeOH/CH2Cl2) to give 7-amino-4-(3-fluoroanilino)pyrido[4,3-d]pyrimidine (185 mg, 65%) as a white solid. 1H NMR (DMSO) δ 9.94 (1H, brs), 9.36 (1H, s), 8.46 (1H, s), 7.91 (1H, brd, J=11.9 Hz), 7.63 (1H, brd, J=8.1 Hz), 7.41 (1H, dd, J=15.7, 7.7 Hz), 6.93 (1H, dt, Jt=8.5 Hz, Jd=2.4 Hz), 6.68 (2H, brs), 6.38 (1H, s)
