Versuchsvorschrift

To a solution of 61 mg trans-4-(2-o-tolyl-chroman-6-yloxy)-cyclohexylamine (0.18 mmol) in 3 ml methanol and 0.2 ml of acetic acid at room temperature 39 mg tetrahydrofuran-3-carboxaldehyde (0.20 mmol) in 3 ml of methanol were added, and 12 mg of sodium cyanoborohydride (0.89 mmol (0.20 mmol) were then added in one portion. Stirring at room temperature was continued for 16 h. The solution was diluted with aqueous saturated sodium hydrogencarbonate solution and the aqueous layer extracted with dichloromethane. The combined organic layers were dried with sodium sulfate and filtered, and the solvent removed under reduced pressure. The crude product was purified by RP-HPLC. 23 mg of (tetrahydrofuran-3-ylmethyl)-[trans-4-(2-o-tolyl-chroman-6-yloxy)-cyclohexyl]-amine and 19 mg of bis-(tetrahydrofuran-3-ylmethyl)-[trans-4-(2-o-tolyl-chroman-6-yloxy)-cyclohexyl]-amine were isolated.
