Reaction Steps

A mixture of 8-(tert-butoxycarbonylamino)-2-naphthol, as described above in Step H, (93 mg, 0.36 mmol), benzyl bromide (64 mg, 0.37 mmol), and Cs2CO3 (146 mg, 0.45 mmol) in dry DMF (3 mL) was stirred, under argon, at ambient temperature for 18 hrs. The reaction mixture was poured into saturated aqueous NaHCO3 (15 mL) and EtOAc (20 mL). The organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by flash column chromatography on silica, eluting with a gradient of hexane −5 to 15% diethyl ether to yield the desired product as a pale solid.
