Reaction Steps

In a sulfonation flask 2,4-dichloro-benzaldehyde (77 g, 0.44 mol), nitroethane (216 ml, 3.04 mol) and ammonium acetate (81.4 g, 1.06 mol) were added to glacial acetic acid (600 ml). The resulting solution was heated to 90° C. for three hours. After removal of the solvent ice-water (400 ml) was added. The solid product was collected by filtration, washed with water and recrystallized from ethanol. 55.9 g (55% of theory) of 2,4-dichloro-1-((E)-2-nitro-propenyl)-benzene was obtained in the form of a yellow solid (m.p. 79-81° C.).
