cis-Decahydro-quinoxaline (0.104 g, 0.74 mmol) was dissolved in DMF (1 mL) and sodium hydride (60% in mineral oil, 0.015 g, 0.37 mmol) was added. After 5 minutes, trifluoro-methanesulfonic acid 2,2,2-trifluoro-ethyl ester (0.137 g, 0.37 mmol) was dissolved in a small amount of DMF and added to the mixture. Stirring was continued for 1 hour at room temperature then the material was diluted slightly with methanol and applied to a 10 g SCX-2 cartridge. This was washed with methanol then eluted using 2 N ammonia in methanol to afford 1-(2,2,2-trifluoro-ethyl)-decahydro-quinoxaline as a pale yellow oil (0.119 g).
