Participants

Reaction Steps

To a solution of 1-(aminooxy)-2,4-dinitrobenzene (117 g, 0.590 mol) in acetonitrile (1.18 L) was added 3-pyridinemethanol (64.1 g, 0.590 mol) at 40° C., and the mixture was stirred for 24 hr. The solvent was evaporated under reduced pressure, and the residue was washed with dichloromethane (1 L×2) to give the title compound (150 g, yield 83%).
