Reaction Steps

A solution of 15 g of 2-chloro-3-nitropyridine, 11.7 g of 5-amino-2-methoxypyridine and 26.1 g of potassium carbonate in 150 mL dimethylformamide was stirred at room temperature for 4 hours and 25 minutes and further stirred at 70° C. for 3 hours and 10 minutes. Ethyl acetate and water were added to the reaction mixture, and the mixture was extracted once with ethyl acetate. The organic layer was washed 3 times with a saturated aqueous ammonium chloride solution and once with brine, and dried over sodium sulfate. The residue was purified crudely by short-column chromatography. From and the resulting black brown oil was extracted with diethyl ether to give 9.10 g of the title compound as reddish brown crystals (39% y.). (2) N2-(6-Methoxy-3-pyrdyl)-2,3-pyridinediamine
