Ammonium Chloride → 4-Cyclopropylbenzene-1,2-diamine

Participants

Reaction Steps

4-Cyclopropyl-2-nitroaniline (178 mg, 1 mmol) was dissolved in absolute methanol (6 mL), and zinc powder (200 mg, 3.1 mmol) and ammonium chloride (800 mg, 15 mmol) were added. The mixture was stirred at room temperature for 16 hours. The mixture was filtered through a pad of celite, and the filtrate was concentrated in vacuo. The residue was partitioned between water (30 mL) and dichloromethane (30 mL). The organic layer was separated, and the aqueous layer was extracted twice with dichloromethane (15 mL). The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo to give 4-cyclopropyl-benzene-1,2-diamine as a brown solid which was used without further purification (130 mg, 88%).
