실험 절차

To 3 g (23.2 mmol) trans-4-Methylamino-cyclohexanol in 120 ml CH2Cl2 were added 4.2 ml (24.4 mmol, 1.05 eq) N,N-diisopropylethylamine followed by 5.96 g (24.4 mmol, 1.05 eq) 4-(trifluoromethyl)-benzenesulfonyl chloride in 50 ml CH2Cl2. The mixture was stirred at RT over night and the organic phase extracted with 1M KHSO4, followed by 5% NaHCO3 and brine. The combined organic phases were washed with brine, dried over Na2SO4 and evaporated. Column chromatography on silica gel with hexane:EtOAc 1:1 yielded 6.0 g (77%) trans-N-(4-Hydroxy-cyclohexyl)-N-methyl-4-trifluoromethyl-benzenesulfonamide as off-white solid, MS: 338 (MH+).
