Reaction Steps

To 335 mg (5.5 mmol) trans-N-[4-(5-{[2-(tert-Butyl-dimethyl-silanyloxy)-ethyl]-ethyl-amino}-pentyl)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide N-oxide in 8 ml THF were added 0.83 ml 1M TBAF at 0° C. The solution was stirred at RT for 1 h, partitioned between EtOAc and an aqueous solution of Na2CO3. The organic phase was washed with brine and dried over Na2SO4. Column chromatography with CH2Cl2/MeOH 9:1 yielded 190 mg (44%,3 steps) trans-N-(4-{5-[Ethyl-(2-hydroxy-ethyl)-amino]-pentyl}-cyclohexyl)-N-methyl-4-trifluoromethyl-benzenesulfonamide N-oxide as colorless oil, MS: 495 (MH+).
