Procedure

A mixture of 4-bromo-2-fluorobenzoic acid (1.0 g) and cyclohexylamine (10 ml) was stirred under reflux for 5 hours. The mixture was poured into ethyl acetate (50 ml) and water (50 ml), acidified with concentrated hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over magnesium sulfate and concentrated in vacuo to give 4-bromo-2-(cyclohexylamino)benzoic acid (1.32 g).
