4-Phenyl-cyclohexanecarboxylic acid → (4-Phenylcyclohexyl)methanol

참여 물질

반응 단계

A suspension of LiAlH4 (0.56 g, 14.8 mmol, 2.0 equiv) was prepared under argon in 50 mL of anhydrous THF (50 mL) kept at 0° C. A solution of 4-phenyl-cyclohexanecarboxylic acid (1.5 g, 7.34 mmol, 1.0 equiv) in 50 mL of THF was added dropwise over a 20 min period. The reaction mixture was stirred at ambient temperature for 1.5 h and then cooled to 0° C. The excess hydride reagent was carefully quenched under argon by dropwise addition of 1 N HCl. After quenching, the reaction mixture was extracted with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated to give the title product as a colorless oil (1.9 g crude) which was used without further purification.
