A mixture of 2-(2-nitrophenyl)acetaldehyde (760 mg, 4.6 mmol) and methoxylcarbonylmethylenetriphenylphosphorane (1.5 g, 4.6 mmol) in toluene (10 mL) was heated at 110° C. for 3 hours. The crude material was purified by silica gel column chromatography eluting with hexanes and ethyl acetate (2:1) to afford the title compound along with (E)-methyl 4-(2-nitrophenyl)but-2-enoate.
