4-Bromo-2-fluoro-3-methylbenzonitrile → 4-Bromo-2-fluoro-3-methylbenzamide

Participants

Reaction Steps

4-Bromo-2-fluoro-3-methylbenzonitrile (11 g, 51.4 mmol) in a 100 mL mixture of TFA-sulfuric acid (4:1, V/V) was stirred at 40° C. for 16 h. After complete conversion of starting material, the reaction mixture was poured into iced-cold water. The resulting solid was filtered off and washed with water and dried to give the desired product (11.24 g, 48.4 mmol, 94% yield) as a white solid. MS (ESI) m/z 234.1 [M+2]+.
