2-[(4-chlorophenyl)methyl]cyclopentan-1-one

Conditions: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In 3-(4-chlorobenzyl)-2-oxocyclopentane carboxylic acid methyl ester (1.0 g, 0.00375 mol), N,N-dimethylacetamide (1 mL) and triethylamine hydrochloride (0.774 g, 0.00375×1.5 mol) were added and stirred at 130° C. for 2 hours, and then at 140° C. for another 3 hours. In the reaction liquid, ethyl acetate and saturated sodium bicarbonate water were added, and the mixture was partitioned. After extracting the aqueous layer using ethyl acetate, 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. at 140° C. for another 3 hours were added the mixture was partitioned After extracting the aqueous layer the organic layer was dried concentrated Thereafter, the dried concentrated product was purified a target product was obtained
