Procedure

To the mixture containing 3-chloro-4-(2-methyl-5-nitrophenyl)pyridine in acetic acid was added Fe dust (5 eq) and the resulting mixture was stirred at ambient temperature for 6 h. To it was then added saturated sodium carbonate to bring it to neutral pH and extracted with ethyl acetate. The organic layer was washed with brine and dried with sodium sulfate and concentrated and passed through a plug of silica to yield 3-(3-chloro(4-pyridyl))-4-methylphenylamine. MS: MH+=218.
