Reaction Steps

To a mixture of iron powder (220 mg, 4.0 mmol) in 4 ml of acetic acid at 80° C. was slowly added a solution of (3-Nitro-5-chloro-pyridin-2-yl)-(2,4-dimethyl-pyridin-3-yl)-methanone (260 mg, 0.89 mmol) in 2 ml of acetic acid. After the completion of addition the mixture was stirred at 80° C. for half an hour and then cooled. The mixture was diluted with ethyl acetate, filtered through celite and the filtrate was concentrated. The residue was purified by flash column (50% ethyl acetate in hexane) to afford 140 mg of title compound as off-white solid. MS: (M+H)/z=262.0.
