Reaction Conditions

Reaction Steps

A solution of ethyl 3-oxo-5-phenylpentanoate (1.1 g) in methanol (50 ml) was cooled to 0° C.-5° C., azidobenzene (600 mg) and 28% sodium methoxide methanol solution (965 mg) were added and the mixture was stirred at 60° C. for 3 hr. Then, 1N sodium hydroxide (10 ml) was added and the mixture was stirred at 60° C. for 1 hr. The solvent was evaporated under reduced pressure and water (20 ml) was added. 1N Hydrochloric acid was added for neutralization and the mixture was extracted with ethyl acetate (30 ml×2). The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate was concentrated under reduced pressure to give the object product (480 mg) as a powder.
