YieldReaction ConditionsOperation in experiment
35.36 g With sodium hydroxide In ethanol for 1 h; Reflux Methyl 2-(4-((2-oxocyclopentyl)methyl)phenyl) propionate (compound 6, 38 g, 154.28 mmol) was introduced into a 500 ml three-necked flask, ethanol (200 ml) was added, refluxed, and sodium hydroxide solution (20.9 g, 30percent by mass) was dropped to the resulting mixture for 1 hour. After completion of dripping, the material was concentrated to dryness. The residue was recrystallized from ethanol-methyl tert-butyl ether to give a white powdery solid (35.36 g, 131.80 mmol). Molar yield 85.43percent, HPLC purity 99.7percent
