실험 절차
Intermediate 8 (2.46 g, 5.4 mmol) was hydrogenated under an atmosphere of H2 (40 psi) using Raney Ni (1.59 g, 27.1 mmol) in THF (120 mL). The reaction was filtered to remove the Raney Ni and the filtrate was concentrated to afford ethyl 3-(6-(4-(benzyloxy)butoxy)-2-pivalamidopyridin-3-yl)propanoate (intermediate 9) (1.76 g, 71.5% crude) as an oil.
