실험 절차

cis-N-(2-Amino-cyclohexyl)-2-methylsulfanyl-4-trifluoromethyl-benzamide (intermediate G) (264 mg, 0.79 mmol) was dissolved in 15 mL acetonitrile. Potassium carbonate (549 mg, 4 mmol) and bis(2-bromoethyl)ether (239 mg, 1 mmol) were added and the reaction mixture was refluxed overnight. The solvent was evaporated off. The residue was taken up in water and ethyl acetate and was extracted three times with ethyl acetate. The combined organic phases were dried on sodium sulfate, filtered and evaporated. Purification of the residue by flash chromatography on silica gel (dichloromethane/methanol/ammonia 100:0:0->140:10:1) yielded cis-2-methylsulfanyl-N-(2-morpholin-4-yl-cyclohexyl)-4-trifluoromethyl-benzamide as a light yellow gum (218 mg, 68%), MS: m/e=403.3 [(M+H)+].
