Reaction Steps

To a solution of N-(1-benzylpiperidin-4-yl)-N′-(4-fluorophenyl)urea (3.0 g) in a mixture of methanol (15 ml) and tetrahydrofuran (15 ml) was added palladium on carbon (10% w/w, 50% wet, 0.6 g), and the mixture was hydrogenated under atmospheric pressure of hydrogen for 8 hours. The catalyst was filtered off, and the solvents were evaporated under reduced pressure to give a residue, which was triturated with diisopropyl ether to give N-(piperidin-4-yl)-N′-(4-fluorophenyl)urea (1.97 g).
