Procedure
1.96 g of 1-prop-2-ynylazepane (compound 4.1) are added, under inert atmosphere, to 4 g of 4-bromo-2-chlorophenyl trifluoromethanesulphonate (compound IIIa.1), 0.062 g of copper iodide, 10 ml of pyridine and 20 ml of triethylamine, followed by 0.457 g of the catalyst dichlorobis(triphenylphosphine)palladium. The reaction mixture is heated at the reflux point for 2 hours, the solvents are evaporated off under reduced pressure, and the residue obtained is taken up in dichloromethane, washed in water and dried over magnesium sulphate. After evaporating off the solvents under reduced pressure, the residue obtained is purified by chromatography on a column of silica gel, eluting with an 80/20 cyclohexane/ethyl acetate mixture; m.p.=192° C.
