Reaction Conditions

Reaction Steps

In 1-(4-chlorobenzyl)-3,3-dimethyl-2-oxocyclopentane carboxylic acid methyl ester (1.0 g, 0.00339 mol), N,N-dimethylacetamide (1 mL) and triethylamine hydrochloride (0.56 g, 0.00339×1.2 mol) were added and stirred at 150° C. for 2 hours. In the reaction liquid, toluene and saturated sodium bicarbonate water were added, and the mixture was partitioned. After extracting the aqueous layer using toluene, the organic layer was dried using anhydrous sodium sulfate and concentrated. Thereafter, the dried and concentrated product was purified using a silica gel column, and a target product was obtained.
