반응 단계

2.36 g of tert-butyl 4-[2-(benzyloxy)-3-(tert-butoxy)propyl]-4-hydroxy-1-piperidinecarboxylate was dissolved in 40 ml acetonitrile, 426 mg of cerium ammonium nitrate was added thereto, and the mixture was stirred at room temperature overnight. Silica gel was added to the reaction solution, and then it was evaporated. It was purified by adsorptive silica gel charged in a non-adsorptive silica gel column with hexane-ethyl acetate to give 547 mg of tert-butyl 4-[2-(benzyloxy)-3-hydroxypropyl]-4-hydroxy-1-piperidinecarboxylate.
