Reaction Steps
To a solution of 2,3-dihydrofuro[3,2-c]pyridine (23.8 g, 200 mmol) in acetonitrile (130 mL) was added 1-(aminooxy)-2,4-dinitrobenzene (55.0 g, 240 mmol), and the mixture was stirred at room temperature for 3 days. Diethyl ether was added, and the resulting precipitate was collected by filtration to give the title compound (57.0 g, yield 89%).
