Reaction Steps

To a mixture of benzaldehyde (30.00 g, 0.283 mole) and 2-pentanone (67.33 g, 0.782 mole) was added 10% aqueous sodium hydroxide (40.00 g, 0.10 mole) and the mixture was heated and stirred at 55-65° C. for 10 hr. The reaction mixture was cooled to room temperature and the aqueous layer was once separated. 5% Brine (20 g) was added and after stirring, the aqueous layer was separated. This step was repeated twice. The low boiling point content such as 2-pentanone, benzaldehyde and the like in the obtained organic layer were distilled away under reduced pressure to give the title compound as a pale-yellow green oil (138-150° C./1.33 kPa). (39.25 g, yield 79.7%)
