Reaction Steps

3-Ethoxycarbonyl-2-methyl-5-(p-nitrophenyl)pyridine (2 g) was dissolved in warm ethanol (70 ml). Iron powder (4 g) was added to the solution followed by water (7 ml) containing 2 drops of 11.5 N-hydrochloric acid. The mixture was refluxed for 1.5 hours, cooled and filtered. The filtrate was concentrated and the residue dissolved in methylene dichloride. The solution was washed with water, dried and concentrated. The crude product was recrystallised from methylene dichloride-petroleum ether (b.p. 30°-40°) to give the title compound (1.23 g), m.p. 137°-8°.
