실험 절차

Under argon atmosphere, a suspension of 1.29 g of lithium aluminum hydride in 40 mL of anhydrous ethyl ether was treated dropwise with a solution of 5.80 g of cis-4-(tert-butoxycarbonylamino)cyclohexanecarboxylic acid methyl ester in 20 mL of anhydrous ethyl ether with cooling in ice, and stirred for 3 hours while allowing to gradually warm to room temperature. The reaction solution was cooled to 0° C., combined a small amount of water to decompose an excessive lithium aluminum hydride. The insolubles were filtered off through Celite, and the filtrate was concentrated, and then the residue was washed with n-hexane to obtain 3.60 g of the desirable compound as colorless crystals.
