Reaction Steps
A solution of PAMA-K (0.600 g, 1.047 mmol) and piperidine (1.0 mL) in DMF (5.0 mL) was stirred at room temperature for 3 hrs. Solvent was evaporated under reduced pressure to give a residue, which was purified by Amberchrom (CG-161C) eluting with MeOH/H2O to give (S)-2-amino-6-((2-tert-butoxy-2-oxoethyl)(pyridin-2-ylmethyl)amino)hexanoic acid (0.256 g, 70%). MS (ESI), 352 (M+H)+.
