[00358] 4-Aminobutyraldehyde diethyl acetal (6.4 g, 39.7 mmol) and mesityl oxide (20 ml, 175.2 mmol) were mixed neat and stirred at room temperature for 1 hour. After this time, the reaction mixture was extracted with 2.5 M HC1 and the extract washed with ether. The aqueous layer was heated at reflux for 3 hours. The reaction mixture was concentrated in vacuo to reduce the volume by -50%. The concentrated aqueous layer was cooled on ice and diluted with methylene chloride (-100 ml). The mixture was basified with aqueous potassium hydroxide and the layers separated. The aqueous layer was further extracted with methylene chloride (100 ml) and the combined organic extracts were washed with aqueous potassium carbonate. The organic layer was dried over potassium carbonate, filtered and concentrated. Purification by flash column chromatography, on silica gel, eluting with neat EtOAc provided the product as pale yellow oil, 3.2 g (48% yield). The mixture can also be purified by distillation from K2CO3 (instead of column chromatography) to afford the ketone in a similar yield.
