Procedure

To 500 mg (10.5 mmol) trans-N-(4-{5-[Ethyl-(2-hydroxy-ethyl)-amino]-pentyl}-cyclohexyl)-N-methyl-4-trifluoromethyl-benzenesulfonamide in 6 ml CH2Cl2 were added 0.2 ml (1.6 mmol) DAST at −78° C. After 3.5 h at that temperature additional 0.2 ml (1.6 mmol) DAST were added and the mixture was slowly warmed to RT over night. The solution was added to a cooled aqueous solution of Na2CO3 and extracted with EtOAc. The organic phase was washed with brine and dried over Na2SO4. Column chromatography CH2Cl2/MeOH 98:2 yielded 125.4 mg (25%) trans-N-(4-{5-[Ethyl-(2-fluoro-ethyl)-amino]-pentyl}-cyclohexyl)-N-methyl-4-trifluoromethyl-benzenesulfonamide as brown oil, MS: 481 (MH+).
