To a solution of 2-furanamidoxime (12.6 g, 0.1 mole) and p-nitrobenzoyl chloride (18.1 g, 0.1 mole) in 500 ml of dry dioxane, 1 ml of BF3 -ethyl ether is added and the mixture is heated to reflux for 16 hours. Evaporation of the solvent in vacuo gives a light brown solid. It is decolorized with Darco (CHCl3) and crystallized from ethanol-acetonitrile to give 19.2 g (75%) of product, m.p. 168°-170° .
