Versuchsvorschrift

To a solution of 2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]acetaldehyde (50 mg, 0.19 mmole), 5 mL DCM and NA2SO4 (134 mg, 0.95 mmole) was added 2-(pyridin-3-yl)ethan-1-amine (31 mg, 0.25 mmole) and the reaction was stirred overnight. NaBH4 (9.5 mg, 0.25 mmole) added, stir 10 minutes, 2 drops MeOH added, stir 1 h, quenched with water, organics separated off and evaporated. The residue was passed through a Gilson reverse phase HPLC to give {2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethyl}[2-(pyridin-3-yl)ethyl]amine, 65.3 mg (71%). LCMS m/z 367.1 (M+1) observed.
