Reaction Steps
A mixture of 2-bromo-4-ethoxypyridine (500 mg, 2.475 mmol), ethane-1,2-diamine (9.9 ml, 150 mmol) and potassium carbonate (685 mg, 4.95 mmol) was stirred under microwave heating at 140° C. for 2 hours. The reaction mixture was filtered, the remaining solids were rinsed with ethanol and the combined filtrates were concentrated under reduced pressure and purified by flash column chromatography (silica, gradient of 2%-100% 7N NH3 in MEOH in DCM) to yield 287 mg of a solid (1.584 mmol, 64%). MS(ESI) m/z=182.0 [M+1]+.
