4-Fluoroaniline → HCID 59256555, compound

Participants

Reaction Steps

CDI (2.2 g, 0.013 mol) was added to a stirred solution of 4,6-dichloro-3-hydroxy-2-nitrobenzoic acid (3.0 g, 0.012 mol) in anhydrous THF (30 mL) and DMF (2 mL). After 40 min, 4-fluoroaniline (4 mL, 0.042 mol) was added. The solution was heated under reflux overnight, cooled, and concentrated to a dark brown viscous oil. The oil was purified via SiO2-gel chromatography (dichloromethane/methanol, 19:1-9:1) to yield 4,6-dichloro-N-(4-fluorophenyl)-3-hydroxy-2-nitrobenzamide as a light brown oil (2.7 g, 65%).
