A mixture of 4-chlorothieno(3,2-d]-pyrimidine (135 mg, 0.79 mmol) and 3-bromoaniline (95 μL, 0.89 mmol) in 2-methoxyethanol (2 mL) is heated to 79° C. for 30 min. The resulting precipitate is filtered and washed with CH2Cl2 to yield 4-(3-bromoanilino)thieno[3,2-d]pyrimidine hydrochloride (195.5 mg, 72%) as a light yellow solid. 1H NMR (DMSO) δ 11.33 (1H, s), 8.94 (1H, s), 8.23 (1H, s), 8.53 (1H, d, J=5.3 Hz), 8.07 (1H, s), 7.77 (1H, d, J=7.9 Hz), 7.6 (1H, d, J=5.3 Hz), 7.48 (2H, m).
