A solution of tert-butyl (1-(pyridin-4-yl)piperidin-4-yl)methylcarbamate (180 mg, 0.618 mmol, 1 eq) in THF (4 ml) was added dropwise at 0° C. to a suspension of LAH (188 mg, 4.94 mmol, 8 eq) in THF (4 ml) and heated for 16 h at boiling temperature. The reaction mixture was hydrolyzed with H2O:THF (9:1, 2 ml) and 10% NaOH solution (0.4 ml) at 0° C., diluted with THF (25 ml) and stirred for 1 h at RT. The reaction mixture was filtered over Celite and the filtrate was concentrated under reduced pressure. The resulting amine was used in the following stage without being purified further. Yield: 150 mg.
