Versuchsvorschrift

A mixture of trans-4-(methylamino)cyclohexyl hydroxy(di-2-thienyl)acetate (intermediate 5; 300 mg; 0.85 mmol), 2-bromoethanol (0.145 ml; 2.05 mmol) and triethylamine (0.36 ml; 2.58 mmol) in 4.5 ml of acetonitrile and 3.5 ml of THF was stirred at 80° C. in a sealed vessel for 16 hr. Additional amounts of bromoethanol (0.145 ml; 2.05 mmol), triethylamine (0.36 ml; 2.58 mmol), acetonitrile (3.5 ml) and THF (3.5 ml) were added and the stirring and heating prosecuted for 24 additional hours. The solution was evaporated to dryness, dissolved in dichloromethane, washed with brine, dried and concentrated. Purification by preparative reversed-phase HPLC (Cl3CH/MeOH from 1:0 to 9:1) gave 76% of the title product as a colourless oil.
