Procedimiento

6.25 ml (69.3 mmol) of butyraldehyde and 19.44 ml (139 mmol) of diisopropylamine were dissolved in 30 ml of benzene, and the mixture was heated under reflux, while removing the water produced, until the production of water stopped (about 15 hours). The solvent was then removed by distillation under reduced pressure, and the residue was distilled under atmospheric pressure. Those fractions of the distillate having a boiling point of from 140 to 160° C. were collected, to give 6.95 g of the title compound as a pale yellow oily substance (yield 65%).
