Reaction Steps

To a solution of 8-amino-2-naphthol (5.0 g, 31.4 mmol) in 200 mL of dimethylformamide was added imidazole (2.4 g, 34 mmol) and tert-butyldiphenylsilyl chloride (8.6 mL, 33 mmol). After 48 hours, water was added and the reaction was stirred overnight. The solution was partitioned between EtOAc and water, washed with brine, dried (MgSO4), filtered, and concentrated in vacuo to provide the titled product (45.0 g). The crude product was purified by silica gel chromatography (10% EtOAc/hexane) to provide the pure titled product.
