실험 절차
Ethyl 6-((tert-butoxycarbonylamino)methyl)picolinate (8.74 g, 31.2 mmol) was dissolved in AcOH and degassed with argon in a reactor (Roth), then catalytical amount PtO2 was added and degassed with argon again. The reaction was stirred at room temperature under H2 (40 bar) for 3 days. 8a was not fully converted. The reaction mixture was filtered through celite, concentrated in vacuo and purified with flash chromatography in EE. The retrieval of 8a was repeated until 100% converted with the same procedure.
