Procedure

A suspension of 2.1 (5.87 mmol) 1′-benzyl-4-methoxy-[1,4′]bipiperidinyl and 1.0 g 10% Pd/C in 50 mL MeOH and 20 mL water was hydrogenated for 8 h at RT and 3 bar hydrogen pressure. The catalyst was removed by suction filtering, the filtrate was concentrated by evaporation i.vac., the residue was triturated with diethyl ether, suction filtered and dried.
