Procedimiento

A solution of 5-bromopentanonitrile (16.20 g) in dry dimethylformamide (100 ml) was added dropwise over 15 minutes to a stirred solution of dibenzylamine (19.73 g) and N,N-diisopropylethylamine (35 ml, 26 g) in dry dimethylformamide (100 ml). The solution was heated (oil bath 110° C.) for 4 hours and was allowed to cool. The solution was poured onto a mixture of saturated aqueous sodium chloride (400 ml) and water (400 ml) and the mixture was extracted with ether (2×200 ml). The extracts were dried (Na2SO4) and concentrated in vacuo to give a mobile oil (30.32 g).
