The mixture was filtered over Celite. The filtrate was concentrated to dryness. To the crude was added water (50 mL). The mixture was extracted with ethyl acetate (50 mL c 3). The combined organic layers were concentrated to dryness. The crude was then purified by flash column chromatography eluting 10% ethyl acetate in petrol ether to afford methyl 4-nitro- 2-vinyl-benzoate (1.58 g) as a brown oil.
