참여 물질

반응 단계

3.2 g of borane/tert-butylamine complex was added to 200 ml of diethyl ether solution containing 15.6 g (0.10 mol) of methyl cyclohexanone-2-carboxylate and stirred overnight at room temperature. An aqueous diluted hydrochloric acid was added thereto to make it weakly acidic, which was then subjected to liquid-liquid separation. The organic layer separated was dried, concentrated and then distilled under reduced pressure to obtain 13.4 g of ethyl 2-hydroxycyclohexanecarboxylate. Yield: 84.8%. b.p. 60° to 62° C. (0.3 mmHg).
