실험 절차
A solution of 15a (9.85 g, 69.8 mmol) and t-butyldicarbonate (18.3 g, 83.8 mmol) in 50 mL of MeOH was placed in a Parr bottle with 20% Pd(OH)2 (2.0 g) and hydrogenated under 50 psi of H2 overnight. The reaction mixture was filtered through a sintered glass funnel and concentrated on a rotary evaporator. The residue was triturated with ether and the solid was collected and dried to give 3.64 g (24% yield) of Boc-amino alcohol 15b.
