Procedimiento

To a solution of 1,4-diaminobutane 1 (n=4; 25.0 g, 0.28 mol) in methanol (50 mL) was added dropwise a solution of acrylonitrile (31.6 g, 0.60 mmol) in methanol (25 mL) at 0° C. After the addition the mixture was allowed to come to room temperature and then stirred for 18 h. Finally, the solvent was removed in vacuo, to give the diamine 2 as a pale yellow liquid, (57.0 g, quant.).
