0.150 g (0.5 mmol) of (2-piperazin-1-yl-6,7-dihydrothieno[3,2-d]pyrimidin-4-yl)propylamine (VII), 0.082 g (0.45 mmol) of 4-bromobenzonitrile (VIII), 0.011 g (0.05 mmol) of palladium acetate, 0.041 g (0.07 mmol) of Xantphos, and 0.204 g (0.6 mmol) of cesium carbonate are placed in 1 mL of toluene, then stirred for 24 hours at 80° C. Then the reaction mixture is combined with water and extracted with ethyl acetate. The organic phase is washed with water, dried, and evaporated to dryness. The residue is purified by chromatography through an RP column using HPLC (column: Microsorb, RP-C18, 300 Å, 10 μm, 21.4*250 mm, eluant: acetonitrile+0.1% formic acid (A), water+0.13% formic acid (B).
