6-(4-Bromophenyl)-4-(4-ethylpiperazin-1-yl)thieno[3,2-c]pyridine (0.96 g) was heated under reflux in the presence of bistriphenylphosphine dichloride (48 mg), triphenylphosphine (174 mg) and cuprous iodide (46 mg), in 2-methyl-3-butyn-2-ol (0.26 g), pyridine (15 ml) and triethylamine (30 ml) for 1.5 hr. The reaction solution was evaporated, and the resulting residue was purified by NH-silica gel column chromatography (ethyl acetate/hexane system), to give 0.80 g of the title compound as a pale yellow oil.
