Reaction Steps

A mixture of 7-amino-4-methylthiopyrido[4,3-d]pyrimidine (167 mg, 0.87 mmol) (described in a previous experimental) and 3-bromoaniline (0.75 mL, 7.8 mmol) is stirred under N2 at 190° C. for 2.5 h, and the precipitate which appears on cooling is recrystallized from PriOH. 1H NMR (DMSO) δ 9.91 (1H, brs), 9.34 (1H, s), 8.45 (1H, s), 8.19 (1H, s), 7.84 (1H, d, J=8.0 Hz), 7.34 (1H, t, J=8.0 Hz), 7.29 (1H, d, J=8.2 Hz), 6.68 (2H, brs), 6.45 (1H, s).
