Reaction Steps
4-Choroindolo[3,2-d]pyrimidine hydrochloride (240 mg, 1 mmol) and 3-bromoaniline (0.33 mL, 3 mmol) in ethanol (3 mL) are heated at reflux under a nitrogen atmosphere for 2 h. Filtration and washing of the collected solids with ethanol, followed by recrystallization from DMF gives 4-(3-bromoanilino)indolo[3,2-d]pyrimidine hydrochloride (288 mg, 77%). 1H NMR (DMSO) δ12.73 (1H, s), 11.42 (1H, s), 9.02 (1H, s), 8.41 (1H, s), 8.28 (1H, d, J=7.9 Hz), 7.95-7.92 (1H, m), 7.84-7.82 (1H, d, J=8.6 Hz), 7.74-7.69 (1H, m), 7.40-7.47 (3H, m).
