실험 절차
A solution of 3.45 g (9.44 mmol) of trans-Methyl-{4-[4-(tetrahydro-pyran-2-yloxy)-but-1-ynyl]-cyclohexyl}-carbamic acid tert-butyl ester and 0.7 g (2.83 mmol) of pyrimidium toluene-4-sulfonate in 25 ml MeOH was stirred at 55° C. for 1.5 h. The reaction was partitioned between aqueous solution of 10% KHSO4/ether (3×). The organic phases were washed with aqueous saturated NaHCO3, 10% NaCl, dried over Na2SO4 and evaporated to give 2.85 g (quantitative) of trans-[4-(4-Hydroxy-but-1-ynyl)-cyclohexyl]-methyl-carbamic acid tert-butyl ester, MS: 281 (M).
