Procedure

A mixture of 2-methoxy-6-(2-nitrovinyl)phenol (29.0 grams, 0.15 mole) and sodium acetate (12.4 grams, 0.15 mole) in acetic anhydride (100 ml.) was refluxed for 4 hours and then poured into ice water. The resulting semi-solid precipitate was dissolved in hot 95% ethanol. Cooling the solution precipitated the crude product which was purified for analysis by chromatography on silica gel with methylene chloride as elutant. The purified 2-methoxy-6-(2-nitrovinyl)phenyl acetate melted at 128° - 129° C.
