To a solution of 3-bromonaphthalene-1-carboxylic acid (0.30 g) in tetrahydrofuran (3 mL) was added 1,1′-carbonyldiimidazole (0.29 g) under ice-cooling, and the mixture was stirred at room temperature for 2 hours. To this reaction mixture was added ammonia water (1.0 mL, 28% aqueous solution), and the mixture was stirred at room temperature for 4 hours. The reaction mixture was concentrated under reduced pressure. To the residue was added water, and the mixture was stirred at room temperature for 15 minutes. The precipitated solid was collected by filtration. The obtained solid was washed with water and 1 mol/L hydrochloric acid, and dried to give 3-bromonaphthalene-1-carboxylic amide (0.28 g).
