Reaction Steps

To a solution of tert-butyl (S)-3-(2-methoxyethyl)piperidine-1-carboxylate (64 g, 263 mmol) in ethyl acetate (100 ml) was added 4N HCl-ethyl acetate solution (320 ml), and the mixture was stirred at room temperature for 2 hr. The solvent was evaporated under reduced pressure to give (S)-3-(2-methoxyethyl)piperidine hydrochloride as a crude product (46.7 g, yield 98%). The obtained crude product was used for Step 4 without further purification.
