Reaction Steps

2-(2-Methylpyridin-3-yloxy)-5-nitropyridine (D8, 81.1 g, 0.35 mole) in ethanol (2L) was treated with tin (II) chloride (232 g, 1.23 mole) in conc. hydrochloric acid (500 ml) and heated to 50° C. for 1 hour. After cooling to ambient temperature, the mixture was basified with 40% aqueous sodium hydroxide solution, extracted into ethyl acetate, dried (Na2SO4) and evaporated in vacuo to afford the title compound (60.3 g, 86%) as a brown solid.
