Reaction Steps
A solution of 4-nitrobenzaldehyde (2 g, 13.2 mmol) and (1-ethoxy carbonylethylidene)triphenyl phosphorane (4.80 g, 13.2 mmol) in tetrahydrofuran (130 mL) was refluxed for 24 hours. The reaction was concentrated in vacuo and was purified by flash column chromatography on silica gel with hexanes and EtOAc to give (E)-ethyl 2-methyl-3-(4-nitrophenyl)acrylate (645).
