Reaction Steps

A mixture of 4.8 g (20.0 mmol) 1-(4-bromo-benzyl)-pyrrolidine, 1.75 mL (30.0 mmol) propargylalcohol, 2.31 g (2.0 mmol) tetrakis-triphenylphosphane-palladium, 381 mg (2.0 mmol) CuI and 7.07 mL diisopropylamine in 100 mL acetonitrile is heated for 14 h at 60° C. under an argon atmosphere. The solvent is distilled off i.vac., the residue is taken up in water, exhaustively extracted with EtOAc and the organic phase is dried over Na2SO4. After the desiccant and solvent have been eliminated the residue is purified on silica gel (EtOAc/MeOH/NH3 95:5:0.5).
