3.3 g (12 mmol) of 4-(1H-pyrrolo[2,3-b]pyridin-3-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid ethyl ester were dissolved in 15 ml of ethanol and 5 ml of THF. Over this solution, 3.3 g of Pd over carbon at 10% were added. The crude mixture was hydrogenated at 30 psi for 48 hours. The catalyst was filtered off and the solvent removed under reduced pressure affording 1.55 g (54%) of 4-(1H-pyrrolo[2,3-b]pyridin-3-yl)-piperidine-1-carboxylic acid ethyl ester.
