Versuchsvorschrift

To a solution of afford (7-ethoxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-propyl-amine (200 μL of a 0.25M solution in 1,2-dichloroethane, 50 μmole) was added 220 μL of a solution of 1-(methylsulfonyl)-4-piperidinecarboxaldehyde (0.25 M in 1,2-dichloroethane) followed by 30 μL DIEA and 300 μL of a 0.25 M slurry of sodium triacetoxyborohydride in 1,2-dichloroethane. The solution was shaken at 25° C. for 48 h under N2. The reaction was quenched with 1 mL 2% NaOH and the mixture was transferred along with 0.5 mL H2O and EtOAc to workup flasks. The flask was shaken, allowed to settle and the aqueous phase was removed and discarded. The organic phase was washed with water, transferred into a tube and concentrated in vacuo. The final product was isolated by preparative RPHPLC (YMC Combiprep ODS-A column, 10-90% acetonitrile: water (0.1% TFA)) to afford (7-ethoxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-(1-methanesulfonyl-piperidin-4-ylmethyl)-propyl-amine (8 mg) 104[M+H]+=409.
