Versuchsvorschrift

To a solution of 0.216 g (0.694 mmol) of 1-(4,5,6,8-tetrahydrofuro[2,3-c]azepin-7-yl)-6-phenylhexan-1-one in 20 ml of acetic acid, 75 mg (0.83 mmol) of 50% aqueous dimethylamine and 68 mg (0.83 mmol) of 37% aqueous formaldehyde were added, followed by stirring at 100° C. for 30 minutes. After the solvent was distilled off under reduced pressure, the residual solution was alkalified with aqueous sodium hydroxide and extracted with dichloromethane 3 times. The combined organic layer was dried over anhydrous magnesium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (ethyl acetate to ethyl acetate/methanol=4/1) to yield the desired product.
