Reaction Steps

4-(2-chloro-5-nitrophenyl)-3-fluoropyridine (1 eq) was stirred with Iron (0), (3 eq), in acetic acid for 10 hours at room temperature. Reaction neutralized with sodium carbonate and filtered to remove iron. Reaction partitioned between ethyl acetate and water. Organic layer separated and washed with brine, dried over sodium sulfate and concentrated to give 4-chloro-3-(3-fluoropyridin-4-yl)benzenamine. HPLC=1.72 min; MS: MH+=223.
