O-Phenylenediamine → N-(2-Aminophenyl)-4-cyanobenzamide

Participants

Reaction Steps

4-Cyanobenzoic acid (294 mg, 2 mmol) and 8 ml of DMF were stirred at room temperature while 1-Ethyl-3-(3-dimethyllaminopropyl)carbodiimide hydrochloride (768 mg, 4 mmol), hydroxybenzotriazole (324 mg, 2.4 mmol), triethylamine (808 mg, 8 mmol) and o-phenylenediamine (432 mg, 4 mmol) were added. The mixture was stirred for 20 hours at room temperature. The mixture was diluted with 400 mL of brine. The solids were collected by vacuum filtration, washed with water and dried under vacuum to give N-(2-aminophenyl)-4-cyanobenzamide (364 mg, 77%) as a grey solid. LC-MS (m/z) 238 (M+1).
