2-AMINO-5-BROMOBENZAMIDE Usage And Synthesis

Chemical Properties

Off-white to light yellow solid

Synthesis

The general procedure for the synthesis of 2-amino-5-bromobenzamide from benzimidic acid,2-amino- (9CI) was as follows: 2-aminobenzamide (1.00 g, 7.34 mmol) was dissolved in acetonitrile (20 mL) at room temperature and N-bromosuccinimide (1.36 g, 7.70 mmol) was added with stirring. The reaction mixture was stirred continuously at room temperature for 0.5 h. The reaction was subsequently quenched with ice-cold water. The resulting precipitate was collected by filtration and the residue was recrystallized with acetonitrile to afford the light yellow solid product 2-amino-5-bromobenzamide (1.47 g, 93% yield) with a melting point of 186-187 °C (literature value: 185-187 °C, 27 °C).
