Reaction Steps

5.70 g (18.0 mmol) 3-(1-benzyl-1,2,3,6-tetrahydro-pyridin-4-yl)-quinolin-2-ol were placed in 200 mL methanol. 1.00 g palladium on charcoal (10%) were added and the reaction mixture was hydrogenated for 3 h at 50° C. under a hydrogen atmosphere. The catalyst was removed by suction filtering and the mother liquor was concentrated to dryness by rotary evaporation.
