A mixture of 6-bromo-2-hydroxy-N-methyl-1-naphthamide (2.50 g), tert-butyldimethylsilyl chloride (1.61 g), and imidazole (912 mg) in DMP (30 mL) was stirred for 2 h at room temperature. After dilution with water, the resulting mixture was extracted with AcOEt. The organic layer was washed with water and brine followed by concentrating in vacuo. The residue was passed through silica gel plug (hexane:AcOEt=1:1). The elute was concentrated, and the residue was washed with hexane to give the titled compound (3.33 g) as colorless needles.
