Participants

Reaction Steps

A suspension of 20 g (0.088 mole) of 3,5-dimethoxy-4-hydroxy-2-nitrobenzaldehyde and 21 g (0.27 mole) of dry ammonium acetate in 400 cm3 of acetic anhydride and 15.8 g (0.26 mole) of nitromethane is heated under reflux for 2 hours. The reaction mixture is cooled, then the precipitate is filtered off. After washing with water, recrystallization from an ethanol-water mixture and drying under vacuum, 13.9 g of the desired product is obtained in the form of orangeish-yellow crystals (yield =58% ).
