Hydrochloric Acid → 3-Bromo-5-fluoroaniline hydrochloride

Participants

Reaction Steps

To a solution of N-(3-bromo-5-fluorophenyl)acetamide (3.5 g, 15.13 mmole) in absolute ethanol (40 mL) was added HCl (50 mL of a 11% aqueous solution). The reaction mixture was stirred while refluxing in an oil bath set at 110° C. overnight. Conc hydrochloric acid (5 mL) was added and stirred for an additional 5 h prior to concentrating under reduce pressure. The resulting 3-bromo-5-fluoroaniline hydrochloride (2.9 g, 85% yield) was used in the next reaction without further purification. Retention time (min)=2.077, method [4], MS (ESI) 192.0 (M+H).
