Procedure

A solution of 1-naphthylaldehyde (624.8 g, 4.0 mol), nitroethane (300.0 g, 4 mol) and n-butylamine (14.8 g, 0.20 mol) was refluxed in ethanol (400 mL) for 24 hours. The mixture was cooled, diluted with methanol (200 mL), and filtered to give 767 g (90% yield) of 1-naphthyl-2-nitropropene. Upon standing, an additional 60 g (97% total yield) of 1-naphthyl-2-nitropropene crystallized from solution.
