Procedure

A solution of 4-[(6-bromohexyl)oxy]-1-butyne (DE 3513885 A1) (288.9 mg) and 1-(cyclopentylsulfonyl)-3-iodobenzene (500 mg) in MeCN (20 ml) and triethylamine (345 μl) was treated with copper iodide (11.78 mg) and dichlorobis(triphenylphosphine)palladium(II) (43.4 mg) and stirred at room temperature for 3 h. The reaction mixture was partitioned between EtOAc and water, the organic phase was dried (MgSO4) and concentrated in vacuo. The mixture was purified by column chromatography (SPE bond elut, gradient 0 to 40% diethyl ether in cyclohexane) to afford the title compound.
