실험 절차

To a solution of 3.1 g (8 mmol) trans-[4-(tert-Butyl-dimethyl-silanyloxy)-cyclohexyl]-methyl-carbamic acid benzyl ester in 20 ml THF, 10.3 ml (1M, 10.3 mmol, 1.3 eq) Tetrabutylammonium fluoride in THF were added at 6° C. and the mixture was stirred at RT for 2 days. Water was added and the phases were separated and the inorganic phase was extracted with ether and EtOAc. The combined organic phases were washed with brine, dried over Na2SO4 and evaporated. Column chromatography on silica gel with a gradient EtOAc:hexane 1:4-EtOAc yielded 1.9 g 1.9 g (92%) trans-(4-Hydroxy-cyclohexyl)-methyl-carbamic acid benzyl ester as orange oil, MS: 263 (M).
