実験手順
To a solution of N-(7-benzyloxynaphthalen-1-yl)(tert-butoxycarbonylamino)acetamide, as described above in Step K, (1.22 g, 3.01 mmol) in EtOH (30 mL) was added 10% Pd-C on carbon (220 mg) and the reaction mixture was stirred under an atmosphere of hydrogen (ca. 1 atm) at ambient temperature for 18 hrs. The mixture was filtered through a pad of celite, washing with EtOH, and the filtrate was concentrated in vacuo to give a crude product. This was purified by flash column chromatography on silica, eluting with EtOAc, to yield the titled product as a pale solid.
