6-Bromo-4-chloro-thieno[3,2-d]pyrimidine (7.73 g, 31 mmol) was dissolved in 50 mL of dichloroethane and 50 mL of t-butyl alcohol, and 5-aminoindole (4.09 g, 31 mmol) were added. The reaction mixture was refluxed for 14 hours, cooled to room temperature, and concentrated in vacuo to afford 13.02 g of (6-bromo-thieno[3,2-d]pyrimidin-4-yl)-(1H-indol-5-yl)-amine. The crude material was used without further purification (83% purity). 1H NMR (400 MHz, DMSO) d 11.1 (s, 1H), 9.62 (s, 1H), 8.38 (s, 1H), 7.63 (s, 1H), 7.49 (s, 1H), 7.35 (m, 2H), 7.10 (d, 1H), 6.40 (s, 1H); LC-MS: 345, 347 (MH+); HPLC RT: 3.77 minutes.
