Reaction Steps

A mixture of 100 g of 2,4-dimethoxybenzaldehyde, 102 ml of nitromethane, 46.4 g of ammonium acetate and 500 ml of glacial acetic acid was heated at reflux for 2 hours and quenched in 700 ml of water. The crude precipitate was recrystallized from ethanol to give 105.57 g of 1-(2,4-dimethoxyphenyl)-2-nitroethylene as a yellow solid.
