実験手順

To a solution of furo[3,2-c]pyridine (960 mg, 8.06 mmol) in acetonitrile (5.0 mL) was added 1-(aminooxy)-2,4-dinitrobenzene (1.77 g, 8.89 mmol) at room temperature, and the mixture was stirred at 40° C. for 15 hr. Diethyl ether was added, and the resulting precipitate was collected by filtration and washed with diethyl ether to give the title compound (2.06 g, yield 80%).

後処理
