b. 4-(4-fluoro)-phenyl-piperidine To a solution of 1-benzyl-4-(4-fluoro-phenyl)-1,2,3,6-tetrahydro-pyridine (45.0 mmol, 12.0 g) in 100 mL MeOH was added 1.0 g of Pd(OH)2 and the resulting suspension was hydrogenated under 200 psi of H2 in a stainless steel bomb for two days. The suspension was passed through a pad of celite and the filtrate was concentrated in vacuo to obtain 4-(4-fluoro)-phenyl-piperidine (7.5 g, 94%) as a viscous oil.
