反応手順
A stirred mixture of methyl trans-2-(4-chlorophenyl)-4-oxocyclohexanecarboxylate (1.05 g, 3.94 mmol) and 1 N lithium hydroxide (5.91 mL, 5.91 mmol) in tetrahydrofuran (5 mL) was heated at reflux for approximately 1 h. After cooling to room temperature, the reaction mixture was poured into 1 N hydrochloric acid/brine (1:1) and extracted three times with methylene chloride. The combined organic extracts were washed with brine, dried (MgSO4) and concentrated in vacuo. The crude title compound was used without further purification in the subsequent reaction.
