Reaction Steps
70 mg (0.17 mmol) trans-N-Methyl-N-[4-(4-oxo-pentyloxy)-cyclohexyl]-4-trifluoromethyl-benzenesulfonamide were treated with 31 μM (30% in ethanol, 0.17 mmol) dimethylamine and 61 μM (0.17 mmol) tetraisopropyl orthotitanate. The solution was stirred at RT for 18 h, additional 31 μM (30% in ethanol, 0.17 mmol) dimethylamine and 61 μM (0.17 mmol) tetraisopropyl orthotitanate were added and stirring was continued for 2 h. The mixture was diluted with 1.7 ml ethanol and 7 mg (0.1 mmol) NaCNBH3 were added, and stirring was continued over night. 0.35 ml water was added and the suspension filtered and evaporated. The residue was purified by column chromatography with CH2Cl2/MeOH 9:1 to give 13.2 mg (18%) trans-N-[4-(4-Dimethylamino-pentyloxy)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide as colorless oil, MS: 451 (MH+).
