실험 절차
A mixture of 10% palladium on carbon (7.5 g) and (−)-4-amino-1-benzyloxycarbonyl-3,3-dimethylpiperidine (cf. Preparation 19, Step 4, 50 g, 191.0 mmol) in methanol (500 ml) was stirred under hydrogen atmosphere (30 atm.) at 30° C. for 6 hr. The catalyst was filtered off, washed with 100 ml methanol and filtrate was concentrated to dryness to afford (−)-4-amino-3,3-dimethylpiperidine, which was further purified by vacuum distillation to give 16.8 (71%) titled compound.
