To 1.0 g (2.18 mmol) trans-N-[4-(3-Bromo-propoxy)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide in 10 ml acetonitrile was added 0.29 ml (3.1 mmol) acetocyanhydrine in 5 ml acetonitrile and 0.37 ml (2.5 mmol) 1,8-Diazabicyclo-(5,4,0)-undec-7-ene in 5 ml acetonitrile. The solution was stirred at RT over night. An additonal amount of acetocyanhydrine and 1,8-Diazabicyclo-(5,4,0)-undec-7-ene were added and the solution stirred at 50° C. for 6 h. The mixture was concentrated and dissolved in water/ether. The organic phase was washed with brine, dried over Na2SO4 and was evaporated to give 366 mg (41%) trans-N-[4-(3-Cyano-propoxy)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide as light yellow oil, MS: 404 (M).
