A mixture of 1-propylpiperidine-4-carboxamide (1.2 g, 7.06 mmol) in 50 mL THF was treated in one portion with LAH (0.98 g, 14.2 mmol). The mixture was heated at reflux for 2 hours. On cooling the excess LAH was decomposed by the stepwise addition of H2O, 1N NaOH, H2O and Na2SO4 (v/v/v/w-1;1;3;12.5 based on 1 gram of LAH). After stirring for 10 min the solids were filtered and washed with EtOAc. The solvent was removed (rotovap) to give 0.9 g of title compound as a yellow oil.
