| Hazard Information | Back Directory | [Description]
Phenyl cyclopentyl ketone (Item No. 31036) is an analytical reference standard categorized as a precursor in the synthesis of ketamine (Item Nos. 19389 | 11630). This product is intended for research and forensic applications. | [Uses]
Phenylcyclopentyl ketone is the key intermediate of synthetic hydrochloric acid amyl ethyl quin ether. | [Synthesis]
In 100ml round-bottomed flask, by 2-cyclopenta ethyl benzoylacetate (10.6g, 43.05mmol, 1.0eq), NaOH (2.6g, 64.5mmol) and Na2CO3(4.5g, 43mmol), is suspended in 50.0mLH2In O, it is warmed up to 80 DEG C and reacts 3 hours, obtain product phenylcyclopentyl ketone.Purify: reactant liquor is cooled to room temperature, extract 3 times with ethyl acetate 20mL；Organic phase saturated sodium-chloride washs, and merges organic phase and uses anhydrous MgSO4Being dried, then remove solvent under reduced pressure, obtain thick product, column chromatography purifies, and eluant, eluent is ethyl acetate: petroleum ether (1:10), obtains 6.54g target product, yield 87.2%. |
