Procedure
To a suspension of magnesium sulfate (10.1 g) in diisobutylamine (72.0 g) was added dropwise valeraldehyde (24.6 g) at 0-5° C. under a nitrogen atmosphere, and it was stirred at 10-15° C. for 1 hour. After ice-cooling, water (60 ml) was added and it was stirred to dissolve the magnesium sulfate. After the removal of the aqueous layer, to the organic layer obtained was added a 9% (w/v) aqueous acetic acid solution (200 ml) at 0-5° C. and then stirred for 5 minutes. The aqueous layer was, then, removed again, a 0.5% (w/v) aqueous sodium hydroxide solution (60 ml) was added to the organic layer at 0-5° C., and stirred for 5 minutes. After stirring, the aqueous layer was removed to afford the title compound (51.3 g, yield: 80%, purity: 93.8%) as a colorless oil.
