Versuchsvorschrift

Trans-4-(methylamino)cyclohexyl hydroxy(di-2-thienyl)acetate (intermediate 5, 0.5 g, 0.001 mol), 1,9-dibromononane (2.9 mL, 0.01 mol) and triethylamine (0.44 mL, 0.003 mol) were mixed together under nitrogen atmosphere and stirred at 70° C. for 94 hours. The reaction mixture was evaporated and purified by column chromatography with silica gel, eluting with chloroform/methanol (from 100 to 4:1) to give the title compound as a brown oil (55%).
