Procedure

A solution of 36.8 g of 2-chloro-4-dimethylaminobenzaldehyde, 18 ml of nitroethane and 15 g of ammonium acetate in 150 ml of absolute ethanol is refluxed for 2 hours. The mixture is then poured into 1.5 l of water, whereupon the compound separates as a viscous red oil, which crystallizes on scratching. Recrystallization from ethanol yields 18.0 g of the compound, melting at 93°-94°.
