To a solution of (3R,5R)-3-(tert-butyldimethylsilyloxy)-5-fluoro-1-(4-methoxybenzyl)piperidine (1 eq) in 5 mL of methanol was added 10% Pd/C (0.2 eq). The resulting suspension was stirred at H2 atmosphere overnight. The crude solids were filtered through a pad of Celite on a paper lined Buchner funnel, washed with MeOH, then concentrated in vacuo to yield (3R,5R)-3-(tert-butyldimethylsilyloxy)-5-fluoropiperidine, which was used to next step without further purification. LC/MS (m/z): 234.1 (MH+).
