실험 절차

To a mixture of acetone (80 ml), sodium hydroxide (1.2 g) and water (80 ml) was added dropwise at 0° C. a solution of 5-chloro-2-methylbenzaldehyde (4.1 g) in acetone (10 ml), and the mixture was stirred at the same temperature for 1 hour. Under reduced pressure, acetone was evaporated, and the residue was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and concentrated under reduced pressure to give 4-(5-chloro-2-methylphenyl)-3-buten-2-one (5.5 g) as oil.
