Reaction Steps
To 60% sodium hydride (0.22 g, washed with hexane thrice) was added ethanol (30 ml). To the mixture was added 5-phenylcyclohexane-1,3-dione (1.0 g) and then was added chloroacetone (0.49 g) at 0° C., and the mixture was stirred at room temperature for 20 minutes and refluxed for 13 hours. Under reduced pressure, the solvent was evaporated, and the residue was dissolved in ethyl acetate. The solution was washed with water and saturated brine, dried with magnesium sulfate and concentrated under reduced pressure, and the residue was purified with silica gel column chromatography (EtOAc/hexane) to give colorless crystals of 3-methyl-6-phenyl-4,5,6,7-tetrahydrobenzofuran-4-one (0.18 g).
