Procedure

To a solution of 10.035 g (104.43 mmol) of 3-furaldehyde and 6.37 g (104 mmol) of nitromethane in 200 ml of ethanol, 11.0 ml of 10 N aqueous sodium hydroxide was added dropwise under ice-cooling, after which the reaction mixture was added dropwise to about 15% aqueous hydrochloric acid; the resulting precipitate was collected by filtration, washed with water and dried to yield 2-(3-furyl)-1-nitroethylene as a brown powder (yield 9.320 g). This crude product, without purification, was used for the next reaction.
