320 mg (corresponds to 0.59 mmol) of crude trans-N-[4-(5-Iodo-pent-1-ynyl)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide in 6 ml MeOH was treated with 0.6 ml (5.93 mmol) of N-methylpropylamine. The reaction was stirred overnight at 65° C. and partitioned between aqueous 1N NaOH /Et2O (3×), the organic phases were dried over Na2SO4 and evaporated. Purification by flash column chromatography on silica gel (CH2Cl2, then CH2Cl2/MeOH 95:5 to 9:1) gave 128 mg (47% over two steps) of trans-N-Methyl-N-{4-[5-(methyl-propyl-amino)-pent-1-ynyl]-cyclohexyl}-4-trifluoromethyl-benzenesulfonamide, MS: 459 (MH+).
