To a cooled (0° C.) solution of lithium aluminum hydride (8 ml, 0.5M in ether) is added, slowly, a solution of 5-(dimethylamino)-pentanenitrile (126 mg, 1 mmol, reference example 94a) in ether (1 mL). On complete addition, the cold bath is removed and stirring continued for 2 h. The reaction mixture is then cooled to 0° C. and quenched by dropwise addition of water (160 mL), sodium hydroxide solution (160 mL, 5M), then a further portion of water (160 mL). The resulting mixture is filtered through celite and the filtrate concentrated under reduced pressure to give an oil which is used without further purification.
