4-(bromomethyl)naphthalen-1-carboxylic acid (7 g), 1-(trimethylsilyl)methylamine (2.7 g), N,N-dimethylaminopyridine (0.1 g) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (6.6 g) were dissolved in dichloromethane (30 ml), and stirred for 5 hours at room temperature. Water was added to the reaction mixture, and then organic layers, were separated and dried over magnesium sulfate. After filtering the reaction mixture, the solvent was distilled off under reduced pressure, and the resulting mixture was purified by silica gel chromatography, to obtain 4-(bromomethyl)-N-[(trimethylsilyl)methyl]naphthalene-1-carboxamide (3 g).
