Methyl 4-(pyridin-4-yl)benzoate (285 g, 1336.57 mmol) and palladium (5% on carbon, 50% wet, JM Type 87L) (57 g, 13.39 mmol) in methanol (2850 mL) were stirred under an atmosphere of hydrogen at 5 bar and 70° C. for 15 hours. The catalyst was removed by filtration and washed with methanol (2850 mL). The solvent was evaporated to dryness to afford methyl 4-(piperidin-4-yl)benzoate (291 g, 99%) as a solid.
