Reaction Steps

Ethyl isonicotinate (10.0 g) was dissolved in tetrahydrofuran (100 ml), and O-(2,4-dinitrophenyl)hydroxylamine (11.9 g) was added at room temperature, which was followed by refluxing under heating for 2 hr. The solvent was evaporated under reduced pressure, and the obtained residue was washed with diethyl ether and ethyl acetate to give the objective compound (10.5 g) as an amber-colored powder.
