To a solution of 4-chloro-6-iodothieno[3,2-d]pyrimidine (0.5 g, 1.7 mmol) in DCE (5 mL)/TEA (1 mL) was added 1-Benzyl-piperazine (0.3 g, 1.69 mmol). The mixture was refluxed for 1 hour. The solvent was removed and the residue was subject to chromatography on silica gel to afford (4-Benzyl-piperazin-1-yl)-6-iodothieno[3,2-d]pyrimidine (0.65 g, 88%). 1H NMR (CDCl3, 400 Hz) δ 8.47 (s, 1H) 7.60 (s, 1H), 7.35-7.23 (m, 5H), 3.95-3.92 (m, 4H), 3.51 (s, 2H), 2.59-2.54 (m, 4H). MS (ESI+) [M+H]+ 437.
