Ammonia → 4-Aminobenzamide

Participants

Reaction Steps

To an ice-cold solution of 4-amino-benzoyl chloride (0.38 g, 2.45 mmol) in tetrahydrofuran (2 ml) was added aqueous ammonia solution (15 ml). The reaction mixture was stirred at room temperature for 12 hr. The solvent was removed under vacuum, water added and the compound was extracted into ethyl acetate. The organic layer was dried and concentrated under vacuum. The crude compound was purified using silica gel column chromatography, using chloroform/methanol as eluent, to yield 4-amino-benzamide (0.1 g, 30%).
