Yield: 99%
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in methanol;1,2-dichloro-ethane at 45; for 4.5 h;chemoselective reaction;Reagent/catalyst;Time;Pressure;Temperature;
Steps:
4.2. A typical procedure for preparation of 4-substituted piperidine hydrochlorides
General procedure: A suspension of 5a (366mg, 2.0mmol), 10% Pd-C (183mg, 50wt%), and ClCH2CHCl2 (320mg, 2.4mmol) in MeOH (30mL) was hydrogenated on an atmospheric pressure hydrogenator (or balloon) at 45°C until the absorption of hydrogen ceased (4.5h). After the Pd-C catalyst was filtered off, the solvent was removed on a rotavapor. The residue was diluted with diethyl ether (10mL) to give the desired product 1a·HCl (419mg, 99%) as a white crystal. The product was collected simply by a filtration and usually was pure enough for any analytical purposes.
