1,5-Dicyanopentane (Aldrich Chemicals) (25.0 g, 205 mmol), sodium hydride (60% oil dispersion; 8.2 g, 205 mmol) and T.H.F. (150 ml) were heated under reflux for 17 hours. After cooling, water (150 ml) was added and the upper organic layer removed, dried (Na2SO4) filtered and the solvent evaporated. Recrystallisation from hot toluene (80° C.) gave the product as beige crystals.
