N-Boc-4-Piperidone (VII) is converted into the enol triflate (VIII) upon treatment with N-phenyl trifluoromethanesulfonimide and LDA. Subsequent Suzuki coupling of (VIII) with 3-acetamidophenylboronic acid (IX) yields the 4-aryl tetrahydropyridine (X). Removal of the N-Boc group of (X) under acidic conditions furnishes the deprotected tetrahydropyridine (XI). Optionally, catalytic hydrogenation of (X) gives rise to piperidine (XII), which is then deprotected by acidic treatment to produce (XIII).
